NEWS: STATISTICS, LAWS AND ALL OTHER LASER POINTER NEWS
This webpage has a chronological list of general laser pointer news. There are separate pages for specific aviation-related incidents and non-aviation-related incidents. In addition, the What’s new at the website page lists major changes, updates, and additions to LaserPointerSafety.com.
We sometimes add older news items; since the list is chronological, items new to this page won’t always appear at the top. You may want to scroll down to see if there are new items since the last time you visited.
The 8th U.S. Circuit Court of Appeals on Friday rejected Michael Smith's defense that he didn't believe the laser would reach the airliner, saying federal law doesn't require prosecutors to show he intended to hit the aircraft.

Associate Health Minister Jo Goodhew said “Early data seems to show that the number of laser strikes on aircraft have plateaued at the same level as last year.” From Jan. 1 to mid-May 2014, there have been 37 laser incidents. This compares with 116 recorded incidents in all of 2013.
The legislation, which took effect March 1 2014, did not make possession of lasers over 1 milliwatt illegal, but it did restrict importation and sales.
Goodhew said over 80 retailers had been visited to remove any over-powered lasers from shelves and to remind sellers of the new restrictions. Tests showed that of 22 lasers suspected of being over 1 milliwatt, 17 were in fact over the limit. Online auction sites have been monitored. Import officials seized 10 lasers as well.
Nine applications have been submitted seeking government approval to import, supply or acquire a laser pointer over 1 mW. Five have been approved and one is being considered. (Presumably the other three were rejected.)

UPDATED June 26 2014: LaserPointerSafety has received some clarifications from Jo Goodhew’s office:
1) The 37 laser strikes were from January 1 2014 to mid-May 2014.
2) A March 5 2014 article in the New Zealand Herald, which stated there were 119 recorded incidents in all of 2013, is incorrect. The correct number is 116 as stated in the main article above.
3) The statistical analysis of the “plateauing” laser incidents in 2014 was done as follows: The 37 strikes from Jan to mid-May 2014 were extrapolated to give an estimated 104 strikes for 2014. This was then compared with the 116 incidents in 2013. Although this indicates that 2014 might be a decrease compared to 2013, “at this stage we are being cautious and describing it as a ‘plateauing’.” [Note: This statistical analysis would be correct if the rate of lasing is approximately equal throughout all months of the year. However, LaserPointerSafety.com has found that the rate varies with seasons; in the U.S. incidents tend to go up during the Northern Hemisphere summer. If New Zealand’s rate also varies significantly with seasons, then the statistical analysis is flawed. It would be better to compare Jan to mid-May 2013 directly with Jan to mid-May 2014.]
Toyota has filed a petition with the National Highway Traffic Safety Administration, seeking to allow the advanced headlights.
A story in Ars Technica goes into more detail about how the laser headlights work, and how companies are advocating for “sensible policy solutions where the tech and car worlds intersect.”
From a June 5 2014 Ars Technica article by Jonathan M. Gitlin
Note from LaserPointerSafety.com: Although automobile headlights are not laser pointers, they do use diodes similar or identical to those in high-powered blue lasers such as the multi-watt Wicked Lasers S3 Arctic handheld. In headlights, laser diodes are used to energize a phosphor coating so that incoherent bright white light is emitted. The small diodes allow the headlight assembly to be lower-profile, giving more flexibility in body design and aerodynamics. They also allow beam shaping to avoiding dazzling other drivers, and aiming the beam in the direction of travel while turning. Our coverage of laser headlights (other stories) can be found here.
Lamda Guard’s “metaAir” film uses metamaterials, also called nano-composites, to reflect one or more laser colors without interfering with normal visibility. According to the company, the film can protect from beam angles up to +/- 50 degrees away from head-on. This has benefits when protecting cockpits against laser strikes, which can come from any angle.
It can be adhesively applied to glass or clear plastic; applications include eyewear, protective goggles and windscreens. Lamda Guard says that the Airbus tests on windscreens will mark the first time an optical metamaterial nano-composite has been applied on a large-scale surface.
The metaAir film can be engineered either to absorb or reflect the desired wavelength(s). For aircraft application, the reflection approach is being used in order to block undesired light wavelengths from entering the cockpit. The reflection bandwidth is currently in the 15-20 nanometer range.
For the most common type of green laser pointer -- responsible for 93% of FAA reported incidents in 2013 -- with a wavelength of 532 nm, the film would block light from about 522 to 542 nm. Additional wavelength blocking can be added as well, such as the 445 nm blue used in powerful handheld lasers such as the Wicked Lasers S3 Arctic that has up to 2 watts (2000 milliwatts) output.
Two key advantages of blocking laser light at the windscreen are that pilots do not have to carry or use laser protective eyewear, and there is absolutely no interference with the visibility of aircraft instruments. In preliminary tests, the anti-laser film had a narrow enough bandwidth that it did not interfere with airport lights seen outside a cockpit.
In addition to piloted aircraft windscreens, Airbus will also be investigating related applications such as UAV camera protection, and sensor protection for satellites and airborne platforms.
The original FBI education and reward program ran from February 11 to April 11 2014 in 12 U.S. cities that had high rates of laser/aircraft incidents. The FBI said the program led to a 19 percent decrease in lasing reports.
The new, nationwide program was announced June 3 2014. The $10,000 reward offer is scheduled to last for 90 days; until September 1.
The FBI said they are working on the educational campaign with the Federal Aviation Administration, the Air Line Pilots Association, International, and state, local and international law enforcement. They are outreaching to schools, teaching teens to not aim at aircraft.
Farivar noted that there were 80 convictions among the 134 arrests. One reason for the conviction rate of 60%: some who were arrested were minors who were never formally charged.
The extensively researched 4,200-word article, dated May 21 2014, was based around the 14-year sentence handed down in March 2014 to Sergio Rodriguez, for his August 2012 aiming of a laser at two helicopters, one medical and one police. Farivar used the case to illustrate many laser/aviation issues, especially about how prosecution is being used to try to educate and deter future incidents.
Farivar interviewed Karen Escobar, who has brought more cases against laser perpetrators than any other federal prosecutor. Her territory includes Sacramento, Fresno, and Bakersfield.
In the article, Escobar was quoted as saying “At sentencing, [Rodriguez] did not accept responsibility for his actions; he blamed his 2- and 3- year-old children. I believe the evidence showed the laser was a dangerous weapon, and there was intention, supporting a guideline sentence of 168 months. I would not call it harsh. I would say it is a penalty that fits the crime, but I believe that it will have a deterrent effect, and I hope it will.”
Farivar noted that, “While 14 years might sound incredibly excessive for an incident that caused no serious or lasting physical injury, much less death, this is the emerging reality for attorneys prosecuting laser strikes. The Rodriguez sentence now serves as an example of what can happen to defendants who don't take plea deals. (The plea deals typically end up being around two years.)”

The action comes after a number of previous measures had failed to stop misuse of lasers.
The NBC Miami “Team 6 Investigators” did a report on laser incidents, how pilots are endangered, and the enforcement effort to find perpetrators. The report aired May 16 2014.
HB1029 was introduced March 12 2014 by Representative Terry Landry, a Democrat from New Iberia. The House passed it by a vote of 97-0 on April 14, and it was sent to the Senate. As of May 13 2014, it had passed the Committee on Judiciary C and was being sent to the Senate floor for a vote. If it passes, as expected, it will be sent to Gov. Bobby Jindal for his signature.
The bill “provides penalties of imprisonment with or without hard labor for not less than one nor more than five years, and a fine of $2,000. For second or subsequent offenses, the offender shall be imprisoned with or without hard labor for not less than two years nor more than ten years and shall be fined $4,000.”
A police officer who testified before the Judiciary C Committee told of an incident where a suspect was tracked down but officers “couldn’t charge him with anything.” The FBI -- who could bring charges -- was given the information but after two months, nothing was done.
A police helicopter pilot was asked why people aim lasers at aircraft. He said “We don’t know their intentions,” and speculated that they could be “just fooling around” or trying to interfere with police work.

TASC is working on countermeasures such as laser eye protection and the development of procedures for injury assessment. The work is being performed under the Optical Radiation Bioeffects and Safety contract with the Air Force’s 711th Human Performance Wing’s Optical Radiation Bioeffects Branch at Fort Sam Houston in San Antonio, Texas.
From the San Antonio Business Journal
The SKY Technologies Blue Handheld includes a keyswitch, 3-5 second emission delay, remote interlock, and a shutter to cut off the beam, as required by FDA regulations enforced by the agency’s Center for Devices and Radiological Health (CDRH). Under current (May 2014) law, the laser appears to be legal for sale and use in the U.S., assuming the manufacturer also submitted a proper Laser Product Report and has filled all other FDA/CDRH import and paperwork obligations.*
Although the agency did not give a reason, such bans have been imposed in other countries in response to climbing numbers of laser illuminations of aircraft as well as reports of eye injuries caused by higher-powered consumer lasers.
The proposal would not make it illegal to own or responsibly use portable, battery-powered lasers of 5 mW or more. However, manufacturers could not make or sell these into general commerce in the U.S.
The agency will accept comments for 90 days (until August 2 2014) on the new proposal. FDA will then review the comments. Based on whether it believes any objections or suggestions are valid, the agency could put the guidance into effect (thus imposing their new interpretation), could submit a revised proposal, or could withdraw its proposal.
What lasers are covered by the proposed 5 mW limit?
FDA does not have direct authority over battery powered portable lasers. For example, the words “pointer” and “handheld” laser do not appear in U.S. laser regulations 21 CFR 1040.10 and 1040.11.
Therefore, to regulate these lasers, the May 5 draft proposes an extension of the FDA’s existing authority to regulate surveying, leveling and alignment (“SLA”) lasers. In the May 5 proposal, FDA asserts that the existing definition of SLA lasers also can applied to lasers with the following design characteristics:
- Compact size (i.e. small, lightweight)
- Battery power
- Ergonomic design to permit hand-held use
- An aperture in the laser product's protective housing to transmit laser emission into open space
- Portability to permit use in open spaces or in unrestricted environments
- Features that utilize the laser’s straight line emission for surveying, leveling, or alignment
According to the FDA, these types of lasers would be affected by the new 5 mW limit:
- Laser pointers
- Tools incorporating laser guides
- Gun sights
- Target designators
- Night vision illuminators
- Visual disruptors
What lasers are NOT covered by the proposed 5 mW limit?
The FDA's proposed 5 mW limit would NOT apply to lasers with the following design characteristics:
- Predictable, stable power input and output
- High quality power supply and/or power conditioning components
- Adjustability of power and wavelength
- Design that facilitates remote actuation
- Hard wire connection to power mains
From the FDA’s Surveying, Leveling, or Alignment Laser Products - Draft Guidance for Industry and Food and Drug Administration Staff webpage, published online May 2 2014. This webpage includes the procedure for submitting comments to FDA.The FDA’s PDF version of the draft guidance document is here.
Editorial comment from LaserPointerSafety.com: We have previously published our opinion disagreeing with the FDA’s interpretation of “SLA” lasers. The existing regulations are clear on what constitutes “surveying, leveling or alignment” (SLA) lasers. While we understand the FDA’s intent, in our view, they are going about it the wrong way. They are essentially “making it up” by adding characteristics (size, battery power) which are in no way derived from the clear, existing definition of SLA lasers. As support of this position, we have not found any surveying, leveling or alignment lasers which look the same as the majority of laser pointers and handhelds. This topic is discussed in much greater detail on our page describing FDA authority over laser pointers and handheld lasers.
The technique is to look in the desired direction with the red aiming beams on, then to switch on the blue beams while looking at the desired target. The glasses have a lens that attenuates blue laser light, so that the user is protected in case of any reflected blue beams.
The two blue beams emitted from Priebe’s glasses, each roughly 1 watt, can burn cloth and pop balloons.
His inspiration: Cyclops’s 2-gigawatt “optic blast,” which is red in the Marvel comic books.
An online YouTube video shows Priebe’s laser glasses in action:
Due to the inherent danger of head-worn lasers, Priebe is not making additional glasses and he is not offering plans for others to build their own.
Priebe has previously built custom laser gadgets such as a replica of Iron Man’s palm-mounted repulsor ray projector, a laser “Gatling gun” with six rotating 1.4 watt blue beams, and a laser gun that emits a non-visible 1 megawatt pulse.

(For reference, the full title of the 5 Feb 2014 document is 2014/59/EU: Commission Decision of 5 February 2014 on the safety requirements to be met by European standards for consumer laser products pursuant to Directive 2001/95/EC of the European Parliament and of the Council on general product safety Text with EEA relevance. The document is online here.)
Timeframe and who is affected
The EU decision does not appear to directly affect laser product sales or access at this time (early 2014). Instead, it applies to European safety standards "pursuant to Directive 2001/95/EC”, the General Product Safety Directive. These standards would need to be updated to conform with the 5 Feb 2014 EC decision. The expected time is about 24 months.
A member of the IEC Technical Committee 76, the group which sets laser equipment safety standards, told LaserPointerSafety.com that "the standardization organizations are about to be requested to produce a new standard or amend an existing one, implementing/specifying such new requirements. The deadline for an amended or new standard seems to be within 24 months…. For now, it seems that the General Product Safety Directive, the Low Voltage Directive, and the Radio & Telecommunications Terminal Equipment Directive are the targeted ones.”
Once one or more standards are updated to meet the requirements of the 5 Feb 2014 EU decision, the new requirements would then be legally enforceable in the European Union.
On March 1 2014, new legislation took effect which severely restricts access to lasers over 1 milliwatts only to those with a legitimate use, such as astronomers.
A Jetstar spokesman said they regarded the pointing of lasers at aircraft as highly irresponsible and welcomed the new legislation.
Air New Zealand spokeswoman Brigitte Ransom said the new regulations were a positive step in mitigating the risks.

The system was developed after a 2002 incident in Kenya where terrorists fired two surface-to-air missiles at an Israeli charter plane carrying more than 250 passengers; the missiles missed their target. C-MUSIC will be added to all El Al aircraft. In addition, the developer Elbit Systems has contracts with other countries besides Israel.

Canada: After 461 lasings in 2013, pilots want stricter penalties plus government controls on lasers
In addition, Capt. Craig Blandford said “We’d (also) like to see a control put on them, some kinds of permits or access to these things that’s somehow controlled. I’m not sure to go so far as to say we want them on a prohibited weapons list, but that’s one of the things that we’re pursuing in order to get stricter on control.”
In 2013, there were 461 laser/aircraft incidents reported to Transport Canada, as compared with 357 in 2012. As of February 12, there have been 44 incidents in Canada during 2014.
From the Ottawa Citizen. The story includes additional details on Canada statistics and the pilots’ proposals.
Other news based on the statistics:
- In 2013, there were no incidents documented by FAA as causing eye injuries. Although there were incidents with eye effects such as temporary flashblindness, afterimage, blurry vision, eye irritation and/or headache, no incidents were serious enough to be tabulated as “eye injuries” by the agency. The FAA did say that in 2013, there were 35 incidents where pilots who were lased sought medical attention.
- The closer an aircraft is to the ground, the greater the likelihood of reporting a laser incident. There is a strong peak in the number of incidents at 1000-3000 feet above ground level.
- The color green was reportedly seen in the vast majority (92.8%) of incidents. Blue was a distant second with 2.4% of incidents.
- For states, California had the most incidents (734), followed by Texas (416) and Florida (326).
- For cities and regions, LaserPointerSafety has determined the Los Angeles area, including Van Nuys and Burbank, leads the nation with 147 incidents. Portland Oregon is second with 137 and Houston is third with 124. (Note that LaserPointerSafety.com tabulates regions slightly differently than the FAA or FBI, so these federal agencies may have slightly different numbers or rankings.)
- FAA tabulates each incident according to the closest airport. For 2013, Portland (Oregon) International led this category with 133 incidents. Phoenix Sky Harbor International was second with 111, and Marin International in San Juan, Puerto Rico was third with 107. This does not necessarily mean that incidents occurred at or near these airports -- just that these were the closest airports to the reported incident.
Full details are on the 2013 laser/aircraft incidents page.
This comes as part of a publicity campaign by the FBI to inform the public and especially teenagers about the dangers of lasing aircraft. The agency said teens are the primary age group responsible for laser/aircraft illuminations.
[Note: There appear to be no official records of perpetrators’ ages. However, here are lists of incidents recorded in LaserPointerSafety.com news items, based on the age of the perpetrator: 10-19, 20-29, 30-39, 40-49, 50-59, 60-69. Counting the stories in each group may give a rough indication of the age distribution of laser perpetrators.]
The two-month campaign will focus on 12 cities with large number of incidents. FBI field offices participating in the regional reward program are Albuquerque, Chicago, Cleveland, Houston, Los Angeles, New York City, Philadelphia, Phoenix, Sacramento, San Antonio, San Juan, and the Washington Field Office.
During the campaign, the FBI and the Air Line Pilots Association International will work with Clear Channel Outdoor to hang billboards and issue public service announcements in these cities, warning people that a laser prank can lead to prison.
Avicii answered “I just bought a really awesome laser pointer. It's two watts, so it's five hundred times stronger than those regular green laser pointers. If you were standing on top of the Empire State Building with it, you could see all the way to Philadelphia. It's dangerous. You can't really play with it. You need to use goggles or you could go blind. But I saw some YouTube videos where it set stuff on fire, and I was like yes. It cost $1,500. That's not too bad for such an amazing invention.”

A video showing the “AirTerminators Super Combat Helicopters” in January 2014 at the London Toy Fair shows an operator getting a brief laser hit just below his eye. The laser is said to be Class 1; if so, such a brief exposure would not be considered harmful according to safety guidelines.
However, it is not recommended for children to play with lasers. Further, it is unknown if the laser remains operational even if the helicopter is stationary or is handheld instead of free flying.
The helicopter is in the middle top of the photo. A red line can be seen just under the operator’s eye. This is the path of the laser from an opposing helicopter as it went across his face during the video frame. This can be seen at 34 seconds into a YouTube video of the demonstration.
Hawks were originally used to scare pigeons away from the modern building, opened in 2004. When these proved unsuccessful, contractors turned to the laser pens. They are primarily used at dawn and dusk to disturb and disperse roosting pigeons.
A spokesperson for the Pigeon Control Advisory Service said “Laser pens can be lethal and blind animals and birds. They are definitely not something we would ever recommend.” PETA, People for the Ethical Treatment of Animals, also said the animals eyes could be damaged and that other humane, non-harmful methods should be used.

Douglas Brandt said that pointers should be labeled as Class 2 [less than 1 milliwatt] or Class 3R [less than 5 mW]. He stated that Class 3B and 4 lasers had the potential to damage the eye and were required to be registered with the State of Illinois.
He urged students to not direct a laser pointer at a person’s eye, and not to use Class 3B or 4 lasers, or unlabeled lasers.
Brandt is the laser safety officer at the university, which has about 11,600 students.

The effort began when NIST physicist and laser safety officer Joshua Hadler worked with the U.S. Attorney’s office on a 2013 case in Fresno, California. Hadler already had devised a relatively simple and inexpensive way to accurately measure laser pointer powers. (His widely-reported study showed that a majority of pointers exceeded the U.S. limit of 5 milliwatts.)
But power is only one factor of the potential laser hazard. The beam spread, or divergence is another key factor. This is because a wide, high-divergence beam will have its energy spread out more, making it dimmer and less hazardous at a distance than an otherwise equivalent-power laser with a narrower, low-divergence beam.
To tackle this, Hadler used a pyroelectric laser camera to measure the laser’s divergence. From the power and divergence, and knowing the approximate distance to the aircraft from the Federal Aviation Administration incident reports, Hadler was able to calculate the irradiance, or laser power over a given area.
The information helped to get a conviction in the Fresno case. Hadler noted that in the past, “...the vast majority of prosecutions were failing, due in no small part to a basic lack of knowledge about the laser devices on the part of nearly everyone in the trial process, including lawyers, judges, and jury members. What they needed was to be able to acquire and present quantitative data about a device's power and its effects at a specified range that could be used in the judicial process."
Hadler will present a paper on February 21 2014 at the American Academy of Forensic Sciences meeting in Seattle, Washington. The paper, “Output Characterization of Handheld Lasers Used in Criminal Aircraft Illumination,” will discuss the needed measurements and will present ideas for having these measurements be done outside of NIST, in law enforcement forensic labs.
Barry Jackson, an A380 pilot and former president of a pilot’s association, cautioned in early January 2014 that this can be “extremely dangerous” for aircraft that are landing.
UFO hunter Alan Ferguson agreed with Jackson’s characterization of the danger. Ferguson lives in Acacia Hills, about 35 miles from Darwin, capital of the Northern Territory. His website, UFOterritory.com.au, contains videos and descriptions of sightings, including some videos of lasers being used to contact or power up UFOs.
Ferguson noted that he and his UFO-hunting associates are “very professional ... and can see the difference between a UFO and a plane ... Especially when they just appear and then move off then stop again, no planes do that.” He said persons who do aim at aircraft are “idiots” and should be prosecuted.
On January 4 2014, laser pointers were aimed at aircraft landing at Darwin International Airport. Ferguson said neither he nor visiting associates used lasers during that time.
Persons who shine a laser pointer at aircraft in the Northern Territory can be jailed for up to four years.
Two frames from a YouTube video shot January 4 2014 by Peter Maxwell Slattery, using a night vision monocular. The first frame shows Slattery aiming a laser at a dot moving steadily across the sky from right to left. The next frame is from a few seconds later and shows the “power up” effect. A YouTube search for “UFO laser pointer” brings up numerous videos with titles such as “UFO’s respond to laser pointers” and “UFO inspects my laser pointer”.
The four Mediterranean islands of Majorca, Minorca, Ibiza and Formentara are popular tourist destinations and are the largest of the group. They are administered as a province of Spain.
The seizures began after authorities discovered laser pointers being sold that were unsafe and/or not labeled according to regulations. Also, pilots were reporting that lasers were being aimed to try to blind the aviators.
Officers from the Directorate General of Public Health and Consumption, the Customs and Border Patrol from the Guardia Civil, and La Palma Local Police inspected the origin and labeling of laser pointers being sold in stores.
Laser pointers are only allowed in toys if they are Class 1 (less than 1 milliwatt) and there is a sign warning parents.
Class 2 laser pointers, between 1 and 5 milliwatts, are for professional use only. Lasers above 5 mW are not allowed to be sold and their use is limited.

Audi Sport Quattro concept car
BMW also has introduced laser headlights, on its electric supercar i8.
The headlights use laser diodes to energize a phosphor that creates white light. According to Audi, the beams have a range of 1640 feet, twice the distance of LED high beams.
Technically, the white-light beam would not have the same coherence as a laser, making it safer for human vision (at least, at normal driving distances -- any very bright light viewed up close could be an eye hazard). An Audi spokesperson said “Our main aim was to not dazzle any drivers, laser technology is much more accurate.”
Because the laser diodes are so tiny -- only a few micrometers in diameter -- the headlight assembly itself can be made smaller as well.
Closeup of the Audi laser headlights
The laser power appears to be about 10 watts, based on an Australian report that “the system is 10,000 times more powerful than a laser pointer”. Such pointers in Australia are limited to 1 milliwatt or 1/1000 watt. It is unclear if this refers to the total power of both headlights, or of a single headlight.
From Car and Driver, and News.com.au. MotorTrend has an excellent article from 2011 describing in detail how the BMW laser headlights work. It contains an account where journalists looked directly into the light without adverse effect.
The Tucson Police Department had about 50 lasing incidents in 2013; the perpetrator was caught in most of the cases. But there was little prosecution.
Orr says the bill is needed because “there’s really no punishment. The county prosecutor, because it's not at a felony status, doesn't go after them. And so literally, you get a ticket and nothing happens. But you're endangering lives."
Orr is working with Tucson police pilot Chris Potter, who says he has been hit by a laser pointer about 100 times in his career. Potter says a laser pointer permanently damaged his right eye around 2011.
According to News 4 Tucson, “the FBI will launch a public awareness campaign about the issue next month.” It was not clear if this was an Arizona-area initiative or nationwide.
From News 4 Tucson
UPDATED February 4 2014 - The Arizona House Judiciary Committee voted in favor of increasing the penalty for persons who point lasers at aircraft. HB 2164 would make it a Class 5 felony, with a presumptive sentence of 18 months in prison, to knowingly or intentionally point a laser at an occupied aircraft. And the penalty would go to 30 months if the act disables the pilot or causes serious physical injury to anyone on board. The legislator who introduced the bill, Ethan Orr, is considering reducing the penalty slightly, to a Class 6 felony, when it goes to the full House. Prosecutors could reduce the charge from a felony to a misdemeanor when appropriate. Orr said this might be the case for youths so that a single mistake would not result in a felony record. From KWST.com. A related article at AZCentral.com includes comments from LaserPointerSafety.com’s Patrick Murphy on the issue.
The regulations were based in part on public submissions made in response to a November 2012 Ministry of Health proposal. Submissions were received from organisations including retailers, government agencies, non-government organisations, professional associations, importers, the aviation industry, members of the public and other organisations with an interest in high-power laser pointers. Their suggestions were compiled in a 20-page document which helped guide the new regulations.
"High-power laser pointers can cause eye injuries, even blindness, and skin burns. ACC accepts around 10 claims a year for these injuries," says Mrs Goodhew.
"They can also cause temporary flash blindness, which poses a serious risk if the person affected is a pilot or in charge of a vehicle or equipment. The Civil Aviation Authority reports around 100 laser strike incidents on planes each year.”
The new controls, under Health and Customs legislation, cover the import, supply and acquisition of high-power laser pointers. They do not currently restrict the possession of high-power laser pointers. A bill is before Parliament which, if passed, would make it illegal to be in a public place with a laser pointer without a reasonable excuse.”
"The new controls have been crafted to only target the high risk hand-held laser pointers with a power output of greater than 1 milliwatt,” Goodhew said. “The regulations are in line with Australia’s restrictions and recommendations by the World Health Organization.”
This compares with five laser incidents during 2012, and one during 2011.
The officials reminded the public that lasing an aircraft is illegal.

“The purpose of this study was to investigate what dose of laser radiation, in terms of intensity and exposure time, may be associated with eye damages. The study has been limited to unwanted exposures of laser radiation from commercially available laser pointers. Of particular interest has been to search for data that clarify the dose-response relationships for functional disabilities that persist more than 6 months.”
“The study shows that long-term vision loss can occur as a result of involuntary exposure from commercially available (strong) laser pointers at close range. The injury may occur before a normal person is able to respond by closing the eyelid, although there are only a few cases reported. A minor such damage is transient within a few days. It is also likely that such a visible injury to the retina becomes functional, i.e. prevents reading skills. What dosage is required for the disability to become permanent is not clear in the literature. Also, the dynamics of evolvement and repair of tissue damages and disabilities are hardly described at all.”

The statement came as hundreds of Arizona law enforcement pilots attended a safety seminar in Tucson focusing on laser beam incidents. In 2012 in Tucson alone, the police department’s air unit had “close to 50 incidents”, according to Potter. As of November 2013, Phoenix was the top U.S. city for laser incidents.

The operation was initiated in August 2013, after multiple incidents of lasers being aimed at aircraft around Portland International Airport. Four law enforcement aircraft were equipped with video surveillance cameras.
On August 10, five aircraft were targeted by a ground-based green laser. One was an Alaska Airlines flight; two were from the FBI and two were from the Portland Police Bureau. At the same time, a surveillance team was on the ground. Using information from the FBI/PBB aircraft sightings, the ground officers observed suspicious behavior from a male in the back yard of a duplex apartment. He was looking up at the sky. He removed something mounted from a stand or pole, and went inside. The laser strikes ceased afterwards.
Six days later, after reviewing the video, consulting Google Earth and Google Maps, and visiting the apartment complex, an FBI Special Agent determined that Apartment 35 -- the one previously surveilled -- was the most likely source of the laser. The apartment was occupied by 39-year-old Stephen Francis Bukucs.
Surveillance cameras were then secretly installed, watching Apartment 35. They could see in daylight, low light and nighttime (using infrared).
The 2013 figure of 3,188 laser/aircraft incidents is 16.7% higher than the same period in 2012. If incidents continue at the same pace, there will be 4,063 incidents in calendar year 2013.
Total Incidents, 2004 to DateThere have been approximately 16,936 laser/aircraft incidents reported to FAA, from January 1 2004 through October 17 2013.
For additional details on previous years, see the year-end statistics for 2012, 2011 and 2010.
Commentary from LaserPointerSafety.com
This 16.7% increase represents a setback from the 2012 totals, which were 3% lower than in 2011. Having a rise in 2013 incidents seems to indicate that the publicity and prosecutions which form the majority of current U.S. anti-laser efforts are not having the desired effect.
There has been some speculation that the 2013 figures differ from 2012 in part because FAA may have updated its incident reporting procedures. While FAA is working to include military and overseas incidents, this has not yet been done. In this respect the 2013 figures are directly comparable to earlier years.
Another possible explanation is that pilots have become more aware of the issue and are thus more likely to report a laser sighting. However, pilot information has been widely available since 2008 and has increased as this became of more concern. By now, most pilots should be alerted to the issue and FAA’s reporting requirements. There has not been a major push during 2013 in this area, so increased pilot reporting is probably not a major factor in causing 2013 reports to increase over 2012.
In his veto message, Christie noted that the New Jersey bill would have gone “well beyond” the federal government’s 5 milliwatt limit for laser pointers. He said there was no criminal use of lasers between 1 and 5 mW in New Jersey. Christie indicated the bill was “arbitrary” and interfered with lawful commerce of pointers typically used in business presentations. (See full text below, after the “Read More…” link.)
The bill was first submitted in November 2010, in response to ongoing problems in Ocean City, N.J. and other beach resort towns where widespread laser pointer sales in boardwalk shops were leading to harassment incidents and aircraft illuminations. The bill, A3169/S418, passed the state Senate on August 19 2013 by a vote of 36-1. It had previously passed the General Assembly on June 24 2013 by a vote of 70-7, with one abstention.
These regulations, 21 CFR 1040.10 and 1040.11, require laser product manufacturers only to self-certify to the Food and Drug Administration that their products meet safety standards. Once the FDA’s Center for Devices and Radiological Health reviews and acknowledges the certification, the laser product can be marketed in the United States.
UL is providing a third-party, independent check on the manufacturer’s claims. This can be provided to retailers such as Amazon.com which in August 2013 began requiring third-party verification of lasers sold on its website. UL can also assist with preparation of a manufacturer’s FDA report.
The company’s free “Evo” app is available on Apple iOS and Android app stores. A smartphone connects to the Evo laser either using a cable from the audio output jack, or wirelessly using an optional $40 Bluetooth module that attaches to the laser. Once connected, the app allows remote control of the laser’s output power, and of its flashing frequency. (Although anyone can download the app, the software does not appear to run unless connected to a Wicked E4 series laser such as the Evo.)
The software code is available as open source, so that hobbyists can create their own software to custom-control the Evo.
Sean Goebel, a graduate student in astrophysics, has produced a 3-minute time-lapse video showing observatories at Mauna Kea, Hawaii, shooting lasers into the night sky. By analyzing how the beam is distorted by the atmosphere, a telescope’s mirror can be counter-distorted in order to obtain sharper images for astronomers.
A still frame from the video. Two telescopes are simultaneously observing the same spot in the Milky Way, using lasers to help give a sharper image.
Goebel writes about the lasers:
“A typical laser pointer that you might use to point at stuff/exercise your cat is about 5 mW. That's five one-thousandths of a watt. Not a whole lot of power. And yet it's enough to blind airplane pilots. The lasers on the telescopes are in the range of 15-40 watts. The FAA calls a no-fly zone over the area when a laser is in use, and two people have to stand around outside in the freezing temperatures and watch for airplanes. Each of them has a kill switch to turn off the laser in case an airplane comes near.”
“Additionally, the telescope has to send its target list to Space Command ahead of time. Space Command then tells them not to use the laser at specific times, ostensibly to avoid blinding spy satellites. However, you could calculate the spy satellite orbits if you knew where they were at specific times, so Space Command also tells the telescope to not use the laser at random times when no satellites are overhead.”
To clarify, the FAA does not have a no-fly zone, but instead issues a “Notice to Airmen” or NOTAM about the laser operations. It is not illegal to fly over the area. Fortunately, at Mauna Kea’s location and altitude only a couple of flights per month fly at night within the laser-affected airspace over the mountain. At one telescope, planes get close enough to the beam to cause a shutoff once every year or twin.
Automated aircraft-detection systems are slowly being tested and phased in, since the cost of having humans watch the skies all night at Mauna Kea’s altitude (13,700 feet) is about $600,000 per year.
The video, “Mauna Kea Heavens”, can be seen at Sean Goebel’s website, which also has more information about adaptive optics lasers and how the video was made. Additional information on aircraft frequency and spotting techniques is courtesy Paul Stomski of the Keck Observatory. A story about Keck’s aircraft protection system appears online in Ascend magazine.
The Association says the lasers are too easily available, and that although it is illegal to aim a laser at an aircraft, the punishments have been too lenient: “Slaps on wrists and £150 fines are not enough.”
According to a September 29 2013 article in the Sunday Express, there were 1,570 laser incidents reported to the Civil Aviation Authority in 2012, and 1,911 in 2011. The most prominent airports cited were Birmingham, Manchester, Liverpool, the East Midlands, Bristol, Heathrow and Gatwick.

They noted that the technique could be scaled up to create laser-powered drones that could do useful work: “commercial laser-powered flight applications are only a few years away.”
The device came to public attention September 28 2013 when gadget blog Gizmodo published an article entitled Holy Crap, This Real-Life Laser Rifle Cuts Through Metal Like Nothing. The article links to TWI’s YouTube video of the laser in action.
The bill was originally introduced November 15 2012. The sponsor, National MP Dr Cam Calder, said the handheld laser pointers “have the potential to cause considerable harm, and put lives at risk when improperly used.” In addition to a penalty of up to three months in prison and up to a NZD $2000 fine (USD $1650), police also would be able to confiscate lasers.
Dr Calder told Parliament that the New Zealand Airline Pilots Association was “very much” in favor of the bill. In 2012, there were over 100 incidents where lasers were aimed at aircraft and moving vehicles.
According to NZ News, “Labor and the Greens supported the bill, although they had concerns the definitions in the bill might be too broad.” Below is the debate on the bill (after the “Read More…” link.) The bill was referred to the Transport and Industrial Relations Committee; their report is due on or before March 25 2014.
In addition, the Ministry of Health is developing regulations addressing the importation and sale of handheld lasers. They are expected to be announced by the end of 2013.
This appears to describe civil cases brought by FAA based on violations of 14 CFR 91.11, which states “No person may assault, threaten, intimidate, or interfere with a crewmember in the performance of the crewmember's duties aboard an aircraft being operated.” The maximum penalty is an $11,000 fine. FAA announced on June 1 2011 its intent to charge laser perpetrators under this law, so the 129 cases referenced above would be since that time.
During the same time period, from June 2011 to September 2013, there were 8,507 reported laser/aircraft incidents in the U.S. This means that 1 out of every 70 reported incidents results in a civil prosecution. Stated another way, 1.5% of all laser/aircraft incidents result in a civil prosecution.
This information was given by a spokesperson for Berlin Tegel airport, speaking after a September 8 2013 incident where a 14-year-old boy aimed a laser at three airplanes landing at the airport.

In a September 16 2013 article, HawaiiNewsNow said there were “dozens” of inquiries about the nighttime green light. One person emailed that the aircraft circled his area about six times at 1:00 am, with a wide green laser that appeared to be scanning downward. Another email confirmed the multiple passes with a V-shaped green laser.
The Army Corps of Engineers is conducting the work. They stated that the laser is not harmful to the eyes. The Oahu work should take about a week, and mapping the entire state should conclude in November.
From HawaiiNewsNow. Similar flyovers using visible green lasers have occurred in other U.S. cities, such as New York City in 2010 and 2012, according to a a brief Google search of such reports, for example here and the comments here.
The laser-projected image appears to be formed by a holographic diffraction grating, similar to those used in “caps” on laser pointers to make simple logos such as faces, dollar signs and other graphics:
Blaze’s inventor, Emily Brooke, put the product on Kickstarter in November 2013 and reached its funding goal within 27 days. The initial cost of a Blaze is £60 (USD $96).
A description at Kickstarter states that when Blaze is off of its bracket on the bicycle, the laser cannot be turned on, as a safety measure. The internal laser will be a “more powerful module than you’d typically find in a laser pointer”. However, because the beam is spread out by the optical element, it will be a Class 2 laser product with human access safety equivalent to a laser pointer that is less than 1 milliwatt.
She also notes that the laser is aimed down onto the road so it will not dazzle drivers.
A police pilot spokesperson said laser users are not reading the packaging which clearly states not to aim at aircraft. After being caught, "There's been a lot of apologies, a lot of regret, some people not realizing the consequences of what they were doing, and then there's been the far opposite -- I can't believe this is happening, this is ludicrous, this isn't serious, it's just a laser pointer."
The pilot also said that a ban is not the answer: "If it's used properly, it's harmless. It's hard to ban something like that, the sale of it completely if 95% of the general public are using it properly."
He noted that not just police aircraft are being lased. Commercial and private aircraft also are at risk.
Edmonton police helicopter pilots are equipped with safety glasses for use during laser illuminations. They have two pair, one to attenuate red laser light and one to attenuate green laser light.

The Army/Navy Piloted Aircraft/Visual and Visible Light/Receiving, Passive Detecting (AN/AVR-2B) Laser Detecting Sets (LDS) uses four sensor units placed on the aircraft. It is smaller, lighter and uses less power than a previous generation developed for the cancelled Comanche helicopter program.
News reports did not state how much it costs to equip each helicopter with an AN/AVR-2B system.

According to HealthNewsDigest.com, “All injuries occurred during play and involved teenage boys and young males, between the ages of 11 and 30. Some injuries were accidental, but others involved a playmate intentionally pointing the laser beam at the victim's eye. The distance between the victim's eye and the laser beam ranged from 1.7 feet to 20 feet (a half-meter to 6 meters). Those who suffered retinal holes were injured at the closest distance, around half meter, or 1.7 feet. Generally, injury from greater distance resulted in less serious damage, the authors of the report say.”
The report was presented August 24 2013 during a Toronto meeting of the American Society of Retina Specialists by Fernando Arevalo, M.D. He is professor of ophthalmology at the Wilmer Eye Institute, Johns Hopkins School of Medicine, in Baltimore Maryland and is also affiliated with the Saudi hospital. Dr. Arevalo hopes that his findings, which were provided to the Minister of Health, will result in changes to how Saudi Arabia regulates handheld lasers.
Using Form 2877, the importer must submit information on each shipment and must affirm that the products comply (or do not comply) with FDA laser regulatory standards. But if a small package omits Form 2877 and is mislabeled (not using the word “laser”), this is an attempt to evade FDA and Customs. FDA specifically notes that such single-package Section 321-type imports do not meet the FDA’s criteria for enforcement discretion for personal importation.
Lasers that FDA is interested in include laser pointers, laser gun sights, laser levels, laser light shows, laser pointer key chains, veterinary laser products, laser illuminators and similar products. If a shipment does not meet FDA requirements, it can then be detained by the FDA and would not be allowed into the country.

The bill was first submitted in November 2010, in response to ongoing problems in Ocean City, N.J. and other beach resort towns where widespread laser pointer sales in boardwalk shops were leading to harassment incidents and aircraft illuminations.
As passed, the bill states that “No person shall sell or offer to sell a laser pointer that exceeds one milliwatt in output power.” A pointer is further defined as “any device that emits laser light to project a beam that may be used for aiming, targeting or pointing out features.”
The penalty is a civil fine of up to $500 for the first offense, and up to $1000 for each subsequent offense. There are two exemptions: for laser pointers intended to be affixed to a firearm, and for a laser pointer used by or under the supervision of a N.J. licensed healthcare practitioner.
If signed in August 2013 by Gov. Christie, it would take effect December 1 2013.
From CBS New York and New Jersey 101.5. The bill’s legislative history and text is available on the New Jersey Legislature website; use the “Bill Search” feature to search the 2012-2013 legislative session for the keyword “laser”.
UPDATED - October 17 2013: The bill was vetoed on October 17 by Governor Christie. In a statement, he noted that the bill would have gone “well beyond” the federal government’s 5 milliwatt limit for laser pointers. He said there was no criminal use of lasers between 1 and 5 mW in New Jersey. Christie indicated the bill was “arbitrary” and interfered with lawful commerce of pointers typically used in business presentations. The full text of Christie’s veto message is here.

The new Amazon.com policy requires pre-approval of laser pointers and related products. The products are limited to Class 3R (5 mW) or less and must be branded; examples include Kensington, Quartet, 3M and Logitech. Products must have a testing report from Intertek, UL or SGS.
It is not known if this is a U.S.-only policy or if it extends to other non-U.S. Amazon sites.
The gadget references the Austin Powers spy spoof movies. In 1997’s International Man of Mystery, the character Dr. Evil asks for “frickin’ sharks with frickin’ laser beams attached to their heads.” In 2002’s Goldmember, his son Scott actually develops the sharks:
In an August 6 2013 press release and Consumer Health Information article, FDA warned parents that lasers operated unsafely can cause serious eye injuries and even blindness. FDA said injuries from lasers can go unnoticed for days or weeks since there is no pain. But vision can slowly deteriorate over time, eventually causing permanent eye damage.
FDA gave the following as examples of children’s toy laser products:
- Lasers mounted on toy guns that can be used for “aiming”;
• Spinning tops that project laser beams while they spin;
• Hand held lasers used during play as “light sabers”;
• Dancing laser beams projected from a stationary column; and
• Lasers intended for entertainment that create optical effects in an open room.
Interestingly, the FDA’s press release and article gave tips on safe usage, including not aiming at car drivers or sports players -- but did not say that it is unsafe and illegal to aim at aircraft.
On August 7 2013, FDA issued draft guidance for industry on minimizing the risk of lasers in children’s toys. Comments are invited within 90 days of the Federal Register publication of the guidance, or by November 4 2013. The draft guidance is reprinted below.
He said that lasers last year, in 2012, were a “fad”. Visitors to the city purchased them from vendors as an impulse purchase
Horry County, which also passed a similar law, has seen similar results. “So far this year, there has been a large decrease in calls concerning the usage of green lasers and zero citations have been issued,” said Lt. Robert Kegler of the Horry County Police.
In the summer of 2012, there were 70 reports of lasers being aimed at aircraft near Myrtle Beach International Airport. The equivalent number for 2013 is not known.
Both ordinances state that adults improperly using lasers will be charged with assault and battery; the penalty is a fine of up to $500 and up to 30 days in jail. They will also be held liable for any damage or personal injury. Minors improperly using lasers will be prosecuted in Family Court, and their parents can be held responsible with a fine of up to $500 and up to 30 days in jail.

UPDATED September 3 2013: A letter from Coast Guard officials had some additional information: “Notable progress has been made, evident through a recent spring break sting operation that found no businesses selling lasers along the beachfront. There were a of [sic] total 68 laser incidents reported to the FAA in 2012 in the greater Myrtle Beach area. So far in 2013, the Coast Guard has not had any of its aircraft illuminated by lasers in the area. We applaud the efforts made by local leaders and sincerely appreciate the community’s support of the initiative.” The August 30 2013 letter was signed by Capt. Ric Rodriguez, Commander, Coast Guard Sector Charleston and by Commander Gregory Fuller, Commanding Officer, Coast Guard Air Station Savannah. From Myrtle Beach Online
The proposal was issued in the Federal Register on June 24 2013. The public may send comments to FDA until September 23 2013. FDA will then evaluate the comments, make any changes as a result, and at a future date will put the amendments into effect.
For consumer lasers, the most significant proposal is to create a new category of specific purpose lasers, “children’s toy laser products.” FDA says these could include lasers intended for creating entertaining optical effects, dancing laser beams projected from a stationary column, spinning tops which project laser beams, or lasers mounted on toy guns for “aiming.” FDA defines such toys as “a product that is manufactured, designed, intended or promoted for use by children under 14 years of age.”
The laser inside such a toy would be restricted to Class I (less than 1 mW for visible light). This is because FDA is concerned that if the toy were broken or disassembled, a higher power laser could harm a child.
Some countries such as Australia and the U.K. have restrictions on lasers starting at 1 mW (3R, 3B and 4), while others such as the U.S. have restrictions starting at 5 mW (3B and 4 only).
The Swedish government invites comments on the proposal, EU notification text, number 2013/0365/S-X00M. This can be done up until October 4 2013 by anyone, whether a national of Sweden or not. At the EU notification link, there are additional links to obtain language-specific versions of the proposal; for example, the English draft text of the proposed laser pointer ban.
Comments can be sent to the EU Contact point Directive 98/34 at:

A new, first-person account from Egypt states that laser pointers were originally used to harass snipers and lookouts using binoculars, and to irritate political enemies. However, the dramatic use of dozens of lasers aimed at Egyptian army helicopters was intended as friendly, being used to “greet” the military who by this time was on the side of the protesters.
(It needs to be noted that, regardless of intent, laser light can flashblind and disrupt pilots. Due to the potential flight and crash hazards, it is illegal in the U.S. and many countries to even aim a laser towards an aircraft.)
This is roughly one-third of the 700 incidents over the same time frame that involved aircraft in or above the West Midlands. (The 480 non-laser incidents included bird strikes, emergency landings, a bomb threat, a dog on the runways and closure of an airfield because of a flying kite.)
On one occasion in July 2011, four different lasers were aimed at a police helicopter in a single incident.
The British Airline Pilots Association asked for prison sentences for persons caught aiming at aircraft, as well as regulations over the sale of high-powered lasers.”
According to West Midlands police, laser attacks on their helicopter have fallen in months prior to July 2013.

The bright rays and the lens flare effects were not captured by the camera but were added later. This may have been done for artistic effect, or to make the lasers look more dangerous. However, this incident does serve as a reminder that “you can’t always believe what you see”.
An aerial view, as seen on Egyptian network Capital Broadcasting Center, gives an idea of what the lasers looked like approaching Tahrir Square. In this scene, there is one blue beam and roughly 30 green beams.
There have been no reports of injuries to the air crews, or of the laser light causing the pilots to lose control. [UPDATE, July 8 2013: A first-person account states that the pointers were friendly, intended to “greet” the army pilots who at this point were on the side of the protesters.]
The laser injury claim rate has increased from about 5 per year to about 13 per year, over the 2000-to-2013 period. The increase works out to 0.73 additional claim per year. This increase is one reason that New Zealand is taking action in 2013 to restrict higher-power handheld lasers.
BALPA general secretary Jim McAuslan asked for a government cross-agency summit to address the problem. BALPA requested stronger regulations restricting the sale of high-powered lasers, more prosecutions, and action taken through trading standards.
He said that hotspots include airports at Manchester, Glasgow, Liverpool and Heathrow.

The LaseReflect Aviator LRG10 glasses are said to mitigate the effects of laser illumination incidents. They reflect more than 99% of 532 nanometer green laser light, the most common color in laser attacks. (According to FAA statistics, about 95% of reported incidents in recent years have involved green light.) They also reflect near-infrared light at 1064 nm, which often is a byproduct of green lasers that are not manufactured with adequate IR-blocking filters. The cost is USD $299.
Custom LaseReflect Aviator glasses are available for specific colors and powers, including multiple wavelengths in a single pair of glasses. For example, blue (405 nm and 445 nm) and red (650 nm) light can also be reflected by the glasses.
This is being posted because some persons may find the ideas presented to be useful. An additional resource is a page at the International Laser Display Association, about damage to cameras at laser light shows.

In 2012 and previous years, FAA was able to release detailed weekly reports tracking the number, type, and other data about laser incidents. But due to budget considerations in 2013, FAA has not yet been able to disseminate any reports. Thus, there is some uncertainty in the 1,500 approximation.
Based on this uncertainty, LaserPointerSafety.com has calculated that there could be between 1% and 16% more laser incidents in 2013 than in 2012. If accurate, any increase would represent a setback from the 2012 totals, which were 3% lower than in 2011. Having a rise in incidents would indicate that the publicity and prosecutions which form the majority of current U.S. anti-laser efforts are not having the desired effect.
The 2013 estimate of 3,774 incidents is based on comparing FAA reports from Jan. 1 to June 12 2013 to the same time period in 2012, and then extrapolating the 8.4% increase over the entire year. However, FAA changed their reporting procedures in 2013 so it is unclear how much of the estimated increase, if any, is an actual increase and how much is due to the new reporting procedures.
For the last comprehensive FAA figures, see our page Latest 2012 laser/aircraft incident statistics.
UPDATE, August 16 2013: New information shows 2,200 incidents from January 1 through August 2 2013. This is an 18% increase over the same period in 2012. Also, it does appear that FAA’s 2013 incident reports are comparable to 2012’s -- they have not yet significantly changed their reporting procedures or criteria. More information is at this LaserPointerSafety.com story.
Because the laser pulse wavelength used was in the infrared, and the cells were cultured (not live retinas) there is no current practical use for pilots and others looking for glasses-free resistance to visible laser light. However, this research may open up other avenues as it does indicate that perhaps the retina can be “hardened.”
The teen was treated at Landspitali University Hospital in Reykjavik. The head physician at the Department of Ophthalmology says the hospital has never seen such a severe case of laser pointer injury.
Lasers in the 1 watt range have been widely available since the mid-2010 introduction of the Wicked Laser Spyder III Arctic blue laser. This is the first handheld 3 watt laser that LaserPointerSafety.com has been aware of.
The new law will not cover low-power lasers below 1 milliwatt which are used for presentations, surveying or gun sights. It will control importation, and will restrict use of higher-power handhelds to “authorized users who have a legitimate purpose such as astronomers, researchers and the NZ Defence Force”, according to an Associate Health Minister.
The study found that helicopters were 3.4 times as likely to be illuminated at altitudes below 2,000 feet than fixed-wing aircraft. Helicopter aircrews were twice as likely to report adverse effects such as distraction, vision interference, operational problems, and pain.
The study also broke down adverse effects by the type of flight, such as commercial, law enforcement, medical and military.
One conclusion of the study is that the “results may also justify the expense of equipping rotary-wing aircraft (particularly law enforcement aircraft) with laser detection and tracking devices to improve the possibility of apprehending perpetrators of these offenses.”
A detailed summary is at LaserPointerSafety.com’s 2013 FAA helicopter study webpage. The full 6-page report is available online from the FAA.
An example of a gun-shaped laser pointer. This particular unit emits a 100 mW beam and costs USD $68. An Internet search turns up a wide variety of gun-shaped novelty and toy laser pointers, including some that also have a lighter built in, and a gag pointer that shocks the user when they pull the trigger.
The bill was introduced by Representative Liston Barfield. He represents Myrtle Beach and North Myrtle Beach, resort towns which have been plagued with incidents of laser pointer harassment by youths and others. In 2012, there were more than 70 area incidents where laser pointers were aimed at aircraft, including Coast Guard search-and-rescue operations that were abandoned due to fear of laser exposure.
This was done after about 40 complaints to police in 2012, most of which "turned out to be kids playing with the laser pointers" according to the deputy police chief. The U.S. Federal Aviation Authority had also contacted the city regarding lasers pointed at aircraft. The ordinance language notes that "the illegal use of laser pointers creates risks and dangers for those targeted by the beam of the laser as well as for the residents of and visitors to the city of North Wildwood.”
Ordinance 1622 had its "first reading" on April 16, meaning it did not become law. The second reading, and possible adoption as a law, was set for the City Council meeting the evening of May 7 2013.

An April 2013 investigation by the Scottish Express found 338 incidents in Scotland from January 1 2011 through February 13 2013. Only 12, or 3.5 percent, had been solved. The paper noted that the International Air Transport Authority (IATA) suggests there are 12 incidents involving lasers each day globally. [Note: The U.S. rate is approximately 9-10 per day, indicating the rest of the world’s rate is 2-3 per day which LaserPointerSafety.com believes to be higher.] An IATA spokesperson said the organization “support[s] strong penalties for anyone caught engaging in the act.”
The U.K.’s Civil Aviation Authority said there were 152 laser incidents at Heathrow Airport in 2012, compared with 136 incidents at Glascow Airport which has 1/10 the number of passengers.
The Scottish Express story contains additional statistics on Scotland airport lasing rates.

Laser pointer hazards for pilots
- A study of the actual output of 40 laser pointers, with powers up to 1.5 Watts, showed significant differences between measured and calculated hazard levels. In some cases, the actual hazard measured at some spots inside the beam was three times the estimated hazard. This is due to the laser output not being smooth in all cases, but instead the beams having “hot spots”. The study also showed that windscreens reduced the beam irradiance -- which is safer for pilots -- from 5% to 60%. (Note however that the McLin study described below showed that windscreens also spread the beam and thus increase glare.)
- A discussion of how being inside the Nominal Ocular Hazard Distance of a laser beam does NOT mean instant blindness for pilots and others.For example, consider a 1 Watt, 1 milliradian laser where the recommended safety distance (NOHD) is 733 feet. If possible, you should be at least 733 feet from the laser before exposing an eye to the direct beam. What is the actual hazard? At 232 feet from this laser, there is a 50/50 chance of the beam causing a barely observable retinal lesion under laboratory conditions where the laser and eye are fixed in place. Due to motion of the aircraft and hand-holding the laser, the chance of a retinal lesion is likely to be less. The distance from 232 feet (“ED50”) out to the NOHD at 733 feet is a known “safety factor” where the chance of retinal injury decreases even further. At the NOHD there is a “vanishingly small risk of hazardous exposure” (Sliney, 2013). Police and other first responder pilots can use this information to better weigh the risk of laser exposure to laser light vs. the benefits of completing a mission (rescuing a person, apprehending criminals, etc.). This presentation also discusses ways to make flight near lasers safer for pilots. A PDF file of all the slides presented is here.

7,378 lasers were seized, along with 8,780 parts from which lasers could be assembled. It was estimated that the company sold over 35,000 laser pointers from 2009-2011, generating income of over £1,000,000 (USD $1,600,000).
Techyun Hii, 33, pleaded guilty to four charges of laser pointer violations and a fifth charge of unsafe power chargers. He was sentenced to a 180 day jail term suspended for 18 months, and to 300 hours of community service. The lasers were later incinerated in a hospital’s furnace.
Lead author John O’Hagan detailed the HPA’s findings in a paper presented at the March 2013 International Laser Safety Conference in Orlando. The case had previously been reported by LaserPointerSafety.com.
The findings were made public at a March 20 2013 meeting of the International Laser Safety Conference.
Researcher Joshua Hadler designed the measurement device to be accurate, inexpensive and easy-to-use. It would cost roughly $2000 in equipment costs to make a copy of the NIST device; plans are available from NIST for interested parties.

The author, Trevor Wheatley, is chair of the Standards Australia SF-019 Committee on laser safety. He studied 41 lasers purchased online in 2012 that were claimed by the sellers to be legal -- lower than the Australian import limit of 1 milliwatt. Most cost less than AUS $20.
Wheatley found that 95% of these pointers were illegal under Australian law, with outputs above 1 mW. Of the 41, 78% were between 5 mW and 100 mW. (5 mW is generally taken to be the highest safe power for a general purpose laser pointer.)
Based on Wheatley's research, "...there would appear to be a greater than 50% chance that someone attempting to buy a 'safe' laser pointer would inadvertently get a hazardous laser." Further, 100% of the tested laser pointers below $20 "would represent prohibited weapons in most Australian states."
From other statistics, the paper states that "availability has not been significantly impacted." In 2007/2008 there were 648 incidents involving lasers pointed at aircraft. In 2010/2011, well after the import and possession restrictions, the number of incidents had increased to 828.
According to a professor at Embry-Riddle Aeronautical University, gold-tinted eyewear has been used by military pilots for laser protection but only works against certain wavelengths of laser light. However, said Dan Macchiarella, if Thomas’ idea “could be applied to lasers of all strengths and wavelengths, that would certainly be a big advancement.”
A March 10 2013 Orlando Sentinel story noted that funding cuts and competition for grants mean that Thomas’ research faces “some serious hurdles” to develop this idea further. Thomas said finding research money is “going to be very difficult, very difficult.”

The Yahoo Sports story noted that laser pens are often misused by European soccer fans. In late February 2013, two world-famous players, Cristiano Ronaldo and Lionel Messi, were targeted during a pair of games.

Josephburg told Yahoo Sports that athletes could be especially at risk, since lasers could cause serious damage from an exposure of a few seconds. He said “If I was a ball player I would be terrified. I only hope that Congress acts on this before some real harm is done.”
Lasers with powers of over 50 milliwatts are dangerous, Josephburg said, and can have serious effects almost immediately. The only effective deterrent is to punish possession or use of high-powered pointers, according to Josephburg: “There is simply no need for a regular person to have one of these.”

US: North Myrtle Beach bans sale of lasers over 1 mW, and bans possession by minors in detailed new law
The changes include:
- Air Traffic Control can now regard a laser illumination of aircraft incident as an “in-flight emergency”, due to the potential debilitating injuries which could compromise safety and interfere with aircrew duties.
- New web-based methods by which pilots can report incidents
- Additional information in the Resources and the Related Documents sections
The key part of the document is the reporting procedure: “On arrival at destination, all aircrews that have been affected by an unauthorized laser illumination are requested to complete the Laser Beam Exposure Questionnaire. The questionnaire is located on the FAA’s Laser Safety Initiative Web site at http://www.faa.gov/about/initiatives/lasers/ and can be electronically submitted. The questionnaire may also be printed and faxed to the WOCC at (202) 267-5289, ATTN: DEN, or emailed to firstname.lastname@example.org.”

From FAA Laser Beam Exposure Questionnaire
What is an FAA-reported “laser incident”?: This is defined as an aircraft pilot seeing one or more laser beams during flight. A mid-2011 study by Rockwell Laser Industries of 6,903 incidents reported to the U.S. Federal Aviation Administration found that in 27% of incidents, beams entered the cockpit (passed through the windscreen). For example, in 2011, there were 3,591 incidents of which approximately 970 (27%) involved beams in the cockpit.
Year-to-Date ComparisonThe 3,482 reported U.S. laser/aircraft incidents in 2012 compare with 3,591 incidents during 2011, approximately 2,836 incidents during 2010, and approximately 1,527 incidents during 2009.
The number of U.S. laser incidents decreased slightly in 2012
Projected 2013 Estimate
If the number of laser/aircraft incidents in 2013 continues to decrease at the same rate as from 2011 to 2012 (-3.04%), then there would be 3,376 incidents in 2013.
Adverse EffectsIn 36 (1.0%) of the 3,482 laser/aircraft incidents in 2012, a pilot or aircraft occupant reported a temporary adverse visual effect such as flashblindness, afterimage, blurry vision, eye irritation and/or headache. In four of the 36 eye incidents, the eye effect may have been more serious or long-lasting. In no incidents, either in 2012 or in previous years, was there any permanent eye damage.
Total Incidents, 2004 to DateThere have been approximately 13,737 laser/aircraft incidents reported to FAA, from January 1 2004 through December 31 2012.
“CDRH recommends (but does not require) labeling on your product that cautions the purchaser with following or similar language: “CAUTION - LASER LIGHT IS BRIGHT AND BLINDING - DO NOT SHINE AT AIRCRAFT OR VEHICLES AT ANY DISTANCE”.
While FDA can require the familiar labels warning against laser eye and skin hazards, FDA does not have statutory authority to require labels for non-health hazards such as laser distraction or temporary flash blinding. Thus, the agency is only able to recommend -- but not require -- the new aircraft/vehicle caution label.
News of the action came in a December 7 2012 FDA email sent to parties including LaserPointerSafety.com. According to CDRH’s Daniel Hewett, the action applies to all “SLA products.” FDA/CDRH considers that laser pointers and handheld lasers are a subset of such Surveying, Leveling and Alignment laser products. SLA lasers are one of the three laser product uses which FDA can regulate under 21 CFR 1040.10 and 1040.11; the other two are medical and demonstration (education/light show) laser product uses.
From a Dec. 7 2012 FDA email. Thanks to Daniel Hewett for bringing this to our attention.
The ordinance would make it illegal to sell lasers over 1 milliwatt, or to sell any green laser to persons under 18. Adults misusing lasers would be charged with assault and battery, with a fine of up to $500, up to 30 days in jail, and being held liable for any damage or personal injury. Minors misusing lasers would be prosecuted in Family Court, plus parents would be held responsible and could be fined or jailed.
In addition, a warning would be required with the sale of every laser pointer.
Under county procedure, it takes three “readings” at council meetings to pass an ordinance. Based on the council’s schedule, the earliest it could be passed would be in January 2013.

The bill does not appear to have any laser power limitation; thus, even possession of a laser less than 1 milliwatts (legal in most countries) would be banned under the proposed legislation.
The key text is as follows:
“13B Possession of hand-held lasers
“(1) Every person is liable to imprisonment for a term not exceeding 3 months or a fine not exceeding $2,000 who, in any public place, without reasonable excuse, has any hand-held laser in his or her possession.
“(2) Any constable may without warrant seize and detain any hand- held laser which there is reasonable ground to suppose is in contravention of subsection (1) of this section.
“(3) On convicting any person of an offence against subsection (1) of this section, the Court may order that the hand-held laser be forfeited to the Crown.
“(4) In this section hand-held laser means any hand-held device, designed or adapted to emit a laser beam.”

A pilot from the Air Line Pilots Association told of his experiences when hit by laser light, and said that “Laser illumination can cause temporary blindness and even permanently damage a pilot’s eyes, potentially leading to an aircraft accident…Individuals must understand the danger and their responsibility to report anyone who misuses lasers.”
The Port Authority of New York and New Jersey is sending officers to schools near airports, to explain the hazards of lasers to children, and to warn them against aiming at aircraft.
An FBI agent said that the bureau is worried about adults and deliberate attacks by terrorists. Fines can range up to $11,000, said an FAA representative. a Coast Guard pilot said that rules requiring helicopters to break off rescues if they are directly lasered, adds to the risk of those the Coast Guard is trying to rescue.
The various law enforcement officials said they were asking the public to call 911 or local authorities if they see misuse, because laser incidents are so frequent and it is rare to apprehend the perpetrators.

From The Age
Commentary from LaserPointerSafety.com: Australia’s laser/aircraft incident rate appears to be 2.8 times the U.S. rate, based on incidents per capita. This is despite the fact that Australia has nationwide import restrictions on laser pointers, and that many Australian states severely restrict or ban possession of laser pointers.
There may be other reasons for this discrepancy. Perhaps laser incidents are not counted the same way in these two countries. Perhaps population is not the best way to compare the two countries’ laser incident rates.
However, on first analysis it appears that Australia has a significant problem with lasers being aimed at aircraft even though widespread restrictions on availability and possession of laser pointers. This is a preliminary indication that bans and restrictions may not work as anticipated. They may need to be combined with other actions, or it may be that other actions have more of an effect to reduce the incident rate.
Calculation details: Australia’s population is estimated at 22,680,322 as of July 25 2012. Australia had 733 incidents in 2011 according to The Age story above. This is a rate of 1 incident for every 30,942 persons. The U.S. population is estimated at 313,979,000 as of the same date. The U.S. had 3,591 laser incidents in 2011. This is a rate of 1 incident for every 87,435 persons.
Illegal imports of laser pointers explode - 24 July 2012
Customs and Border Protection is warning travellers and online shoppers about Australia’s tough laws prohibiting the import of laser pointers.
This follows a dramatic increase in the number of these dangerous items being seized by officers at the border.
In the past year, the number of laser pointers seized by Customs and Border Protection officers at the Sydney International Mail Centre alone has increased by close to 60 per cent, from around 9,000 to over 14,000.
Australian import officers spill out a container full of confiscated packages of illegally-imported laser pointers.
Importing laser pointers greater than one milliwatt in intensity is prohibited in Australia without a permit.
“The sheer volume of these importations suggests that people do not understand the threat these items pose to safety, particularly to commercial aircraft,” said National Manager Cargo Operations, Jagtej Singh.
Customs and Border Protection officers are trained to detect prohibited and restricted items from the millions of items which arrive each week.
“If you try and import laser pointers without a permit, there’s a high possibility they’ll be found by Customs and Border Protection, seized, and you may even face fines of up to $275,000.”
Customs and Border Protection has produced a video clip outlining the risks being taken by people who inadvertently or deliberately breach the laws on laser pointers.
It can be viewed on the agency’s YouTube channel.
According to this video, “Customs officers screen all incoming mail imported into Australia, and items such as laser pointers WILL show up on X-ray.”

33-year-old Techyun Hii ran Sky Laser Pointers from his home in Ribbleton, a suburb of Preston, Lancashire. In 2011, Lancashire Trading Standards officials found he had lasers that were up to 150 milliwatts, substantially over the U.K. limit of 1 milliwatts for laser pens sold to the public through an eBay store. Three packages were being sent to Greece, just before the Greek riots. He had been warned twice before about U.K. laws and his obligations.
In April 2012, investigators placed a test purchase which led to Hii’s arrest. He pleaded guilty to five counts of selling illegal goods, and will be sentenced July 4 2012.

According to the Toronto Star, from January 1 to late May 2012 there have been 36 laser incidents at Pearson International and other Toronto-area airports, and 100 incidents nationwide. (This is probably based on their own analysis of the CADORS incident database since the Transport Canada chart above only went through the first quarter of 2012.)
WestJet has arranged for a Calgary-based ophthalmologist to examine pilots’ eyes after laser incidents. A spokesperson said “We want to have an individual identified in every major city so we can send that (pilot) right away to be tested.”
Canada lags other countries in aggressively prosecuting offenders, according to the chair of the flight safety division of the Air Canada Pilots Association: “The judicial system should apply the law to its maximum extent rather than soft-shoeing around the issue.” At the federal level, aiming a “directed bright light” at an aircraft is illegal under the Aeronautics Act. The maximum penalties are a prison term of five years and a fine of $100,000.

UPDATE, May 30 2012: At LaserPointerSafety.com’s request, Transport Canada analyzed first quarter incident statistics for the past three years. They found 29 incidents in Q1 2010, 27 incidents in Q1 2011, and 53 incidents in Q1 2012. (Note that they found two additional Q1 2012 incidents which were not included in the province-by-province breakdown above.) A Transport Canada spokesperson speculated that reasons for increased incidents in general may include increased awareness and reporting by pilots, and “copycat” actions by persons who would not think to aim a laser at aircraft until they hear news reports of incidents.
The bill amends the Commonwealth’s Acts of Assembly Chapter 5.1-22, covering interference with aircraft to also prohibit “projecting a point of light from a laser, laser gun sight, or any other device that simulates a laser at an aircraft…” The only exception is for persons authorized by the Federal Aviation Administration or by U.S. armed forces. Violation is a Class 1 misdemeanor, punishable by up to 12 months in jail and/or a fine of up to $2,500.

According to Arora, it “passed the House of Delegates in March  but ultimately failed to reach a vote in the state Senate during the final hours of the regular legislative session, when a budget showdown between the two chambers effectively killed scores of bills that were scheduled for votes.” It was reintroduced in November 2012, as discussed in this story.
AIRCRAFT LASER ATTACK BILL PASSES MARYLAND HOUSE, MOVES TO SENATE
Bill Would Punish Shining Laser Pointers at Pilots in Flight
ANNAPOLIS, Md. -- A measure aimed at curbing a dangerous trend targeting aircraft passed the Maryland House of Delegates Monday afternoon and now will head to the state Senate for approval.
The bill, the Laser Safety Act (HB 130), sponsored by Maryland State Delegate Sam Arora (D-Montgomery Co.), seeks stiffer penalties for people who shine laser pointers into aircraft cockpits, potentially blinding pilots in flight. The Act would carry a penalty of up to three years in prison and/or a fine of up to $2,500. Current law only permits for a $500 fine for “misuse of a laser pointer”.
- U.S. airports had 9,079,000 flights in 2011, with 3,591 laser incidents reported to the Federal Aviation Administration. This is a rate of one U.S. laser incident for every 2,528 flights. Said another way, this is 0.40 incidents per 1,000 flights.
- U.K. airports had 2,152,787 flights in 2011, with 1,909 laser incidents reported to the Civil Aviation Authority. This is a rate of one U.K. laser incident for every 1,128 flights. Said another way, this is 0.89 incidents per 1,000 flights.
The ratio of U.K. to U.S. rates is 2.24, meaning that the U.K. had more than twice the number of laser incidents than the U.S., when adjusted for the number of flights. (Important note: These figures do NOT mean that commercial aircraft are targeted at the rates indicated. Many laser incidents involve police helicopters. The analysis is simply meant to compare the two countries’ rates of laser misuse against aircraft of all types.)
It should also be noted that there could be many underlying factors affecting the precise numbers. For example, it is not known if the U.S. counts laser incidents in the same way as the U.K.
However, the figures do indicate that the U.K. rate of laser incidents appears to be significantly higher -- roughly twice the U.S. rate, based on the number of flights.
From an analysis by LaserPointerSafety.com, March 22 2012.
Updated May 27 2012 to correct a math error and make clear that it is the United Kingdom which has a higher rate of laser incidents (e.g., more incidents per 1000 flights). Our thanks to Brian Turner for pointing out this error.
Methodology: We define a “flight” as a takeoff plus a landing. US flight figures are from the Airline Activity “departures” statistic from the Department of Transportation’s Bureau of Transportation Statistics. It is assumed that each flight which departs also lands, so the data is accurate for “flights” as we have defined it. UK flight figures are from totaling column G, Total ATMs, from “Table 4, 1 Air Transport Movements 2011” found on the CAA UK Airport Statistics 2011 page. A UK “movement” is one takeoff plus one landing, so this is the same as our “flights” definition.
While the flight statistics compare only airline (US) and air transport (UK) flights, and do not include law enforcement flights, we believe this is a valid “apples to apples” comparison of how many more flights take place in the U.S. than in the U.K. A previous LaserPointerSafety.com analysis showed that law enforcement flights are less than 1% of the total flights from U.S. airports. Inclusion of law enforcement flight numbers would not significantly change the ratio of U.S.-to-U.K. flights.
The proposed bill would 1) establish the offense of unlawful pointing of a laser device at a law enforcement officer, and 2) prohibit aiming a laser pointer or projecting a laser on or at an aircraft or the flight path of an aircraft. The legislative history of the bill, including the full text of the Senate and House versions, is at the Georgia General Assembly website. We have also put the full text of the House version on the U.S. laws page here at LaserPointerSafety.com.
One interesting point is that the bill contains an exemption for “laser or laser pointer airspace uses that have been reviewed and approved by the Federal Aviation Administration.” This is a broader provision than the recently passed U.S. law, which only permits certain FAA-reviewed uses such as research and development.
In the view of LaserPointerSafety.com, the Georgia bill’s language is more flexible and still maintains safety, since they leave it up to the FAA to determine what outdoor laser uses are approved (technically, “non-objected”).
In 2011, a law was introduced by MP Greg Mulholland (Leeds North West), to make it a criminal offense to shine a laser into an aircraft cockpit.
According the Civil Aviation Authority, there were 1,909 laser incidents in the U.K. in 2011, compared with three in 2008. [Note from LaserPointerSafety.com: The 2008 statistic is almost certainly incorrect. A previous LaserPointerSafety.com news item from BBC News reported 27 lasers were used against commercial aircraft in 2007, and there were 80 cases from January through September 2008.]
From the Bradford Telegraph and Argus
One speaker noted “…we have had kinetic weapons for 500 years and laser weapons for 10-15 years…. The soldier wants a reliable, easy-to-handle, clear to understand system that has the reliability of a normal M16 rifle, or whatever, therefore the superiority is on the kinetic side.”
Two-frame animated GIF showing bright and dim light from the Lozano Observatory (center) near the city of San Antonio (left). North is to the right in this photo from the International Space Station, taken by astronaut Don Pettit. Click on photo for a larger version.
The spotlights were flashed at the ISS by holding plywood sheets in front of the lights every two seconds. This procedure can be seen in the video below.
The animated GIF above shows a bright blue light alternating with a dim light. The bright light is almost certainly from the spotlights. The bluish tint may be an artifact of oversaturating the camera’s sensor. Astronaut Don Pettit reported that the bright light appeared white, and the dim light appeared blue. He wrote “We could only see the laser when the white light was off and not all the time.” (E.g., the white spotlights overpowered the blue laser.) He added, “It was like there were tracking issues with the laser to keep it on target.”
The dim light in the animated GIF may be the laser only, or it may be light from the spotlights that wasn’t fully blocked by the plywood sheets. The astronomers will be working with Pettit, trying to pin down exactly how visible the laser light was.
Author John Wills notes that laser sights are not as effective beyond 20 feet, and they do not substitute for marksmanship techniques such as grip and stance.

Green laser sights are now available; they are more easily seen than an equivalent-power red laser. Infrared laser sights are made for use with night vision goggles. The beam cannot be seen by the naked eye, so a bad guy does not even know he is being targeted.
Wills concludes by saying “like any other tool there is a right way and a wrong way to use” lasers.
A person wearing NVGs is normally not at risk of retinal injuries, since direct laser light falls on the image intensifier device and not the eyes. (Depending on the NVG mounting style, it may be possible for direct laser light to enter from the side or from parts of the vision not covered by the NVG optics.) However, a serious concern is with laser light causing “blooming” of the night vision enhanced image, or even damaging the NVG sensor. To help prevent this, Night Flight Concepts developed “Laser Armor” Light Interference Filters.
Company consultant Dr. Dudley Crosson says the screw-in filters “allow the goggles to function normally by reducing the blooming effect significantly.” A Laser Armor product sheet says the filters reduce blue (445-450 nm) intensity by 97%, and reduce green (532 nm) intensity by 99.5%.
From Aviation Today and a Night Flight Concepts press release
Hickton noted that the new law makes it easier to prosecute since malicious intent is no longer required. Instead, it must be proven that the defendant “knowingly” targeted an aircraft or its flight path with a laser pointer. The new law’s penalty is up to $250,000 fine and/or prison for up to five years.
A map from the FAA Allegheny Flight Standards District Office shows the location of 51 laser events between September 2009 and October 2011. Arrests were made in only two of these cases: “Hickton and other officials concede it can be difficult to pinpoint culprits.”

From Emirat Alyoum. English-language reports from Emirates 24/7 and Bikya Masr.
DragonMart in Dubai claims to be “the largest trading centre for Chinese products outside mainland China,” with almost 4,000 shops. A Gulf News reporter found shops selling lasers under-the-counter for AED 40 to AED 80 ($11-$22). An internet search turned up lasers for sale in Dubai and Abu Dhabi around AED 500 ($136) that were described with terms such as “draw a line in the sky,” “extremely bright green,” and could cause “permanent eye damage”.
The article noted that United Arab Emirates officials have said that illegal use of lasers could lead to fines and jail time.
From GulfNews.com and DragonMart. We have found two articles about youths in Abu Dhabi being arrested after aiming lasers at a helicopter, in June 2010 and in October 2007. Video of the June 2010 incident, uploaded by the Abu Dhabi Police, is available on YouTube (click the photo to go to the YouTube page).
Violation can result in a fine and/or imprisonment up to five years. The bill does provide a few exemptions for research and development, flight testing, the Department of Defense, and the Department of Homeland Security. The only exemption for ordinary citizens is when “using a laser emergency signaling device to send an emergency distress signal.”
The laser pointer misuse prohibition becomes part of the United States Code; specifically, Title 18, Chapter 2, new section 39A: “Aiming a laser pointer at an aircraft”. The text of the new law is here.

Range diagram from a PDF product brochure for the GLARE Enforcer laser dazzler
While the nominal ocular hazard zone (NOHD) at full power is 130 feet, the device includes a safe, low-power laser that measures the distance to a person or reflective object, and lowers the light level so it is safe at the detected distance. Military dazzlers do not have such a feature, relying instead on training soldiers not to aim the laser at persons closer than the hazard distance.
Laser journalist Jeff Hecht reported in a February 13 2012 article that there have been “some injuries” from military dazzlers, most of them minor. He also noted that ordinary citizens armed with laser pointers could be more of a hazard than police or military dazzlers. For example, lasers were used against police in Greece during riots in June 2011.

This is important because the FAA Laser Incident Database sometimes listed multiple reports from aircraft on a single spreadsheet row, if these were all in the same location at about the same time. Thus, it might appear that there was one “incident” which was reported by multiple aircraft. (This is how LaserPointerSafety.com interpreted an “incident” prior to February 15 2012.) However, FAA is now saying this was not their intent. While FAA may suspect that a single perpetrator was involved, they cannot be certain and thus to FAA this would be multiple incidents.
For example, in 2011, there were 12 spreadsheet rows that listed two or more aircraft as seeing the same laser. One row listed 5 aircraft, one row listed 3 aircraft, and ten rows listed 2 aircraft. Thus, there were 28-12 or 16 additional incidents according to FAA’s clarified definition.
The statistical analysis at LaserPointerSafety.com here and here reflects how FAA counts incidents.
Co-sponsor Sam Arora said “We need this law … we’re talking about potential death.” The Maryland State Police testified in support of the bill at a February 7 2012 hearing that “the results [of a laser incident] could be deadly.” A WJZ TV news report said “Blinding a pilot at night is a good way to kill people.”
The bill only applies to laser pointers, defined under Maryland law (Title 3, Subtitle 8, Section 3-806) as any device that emits visible laser light. There are exemptions for lasers used for flight testing for the Federal Aviation Administration, the Department of Defense and the Department of Homeland Security.
The bill was introduced January 23 2012, and had its first reading on February 7. A companion Maryland Senate bill is expected to be introduced soon.
From Essex-Middle River Patch, CBS Baltimore WJZ, and the Maryland legislative information website. The full text of the bill is here; the Maryland definition of laser pointer is here.
Editorial note from LaserPointerSafety.com: A Maryland state police paramedic gave an erroneous demonstration to reporters purporting to show how a laser can be a hazard to aircraft. In a hangar, he aimed a red laser pointer at a helicopter windscreen only a few yards away. The resulting (grossly inaccurate) video shows a tiny red dot on the windscreen and in the aircraft. This is NOT what happens in a laser-aircraft incident. Instead, the light would be many inches across, even at low, helicopter-hovering altitudes of many hundreds of feet. The windscreen would further spread the light so that there would be a wide area of glare. In other words, the hazard is not a pinpoint that can go into one’s pupil, but a large “blob” of light that can cause temporary flashblindness, glare or distraction. This is an example of how laser hazards close up (within a few feet or yards) are very different from laser hazards to aircraft hundreds or thousands of feet away.
There are currently no restrictions on the public’s ownership of lasers in New Zealand.
NZALPA’s technical director Stu Julian told TV ONE that if the laser incidents continue, they could cause a crash due to distracting a pilot when they have minimal reaction time.
According to the New Zealand Civil Aviation Authority, there were 100 laser pointer incidents in 2011, with 40 of those at the Auckland airport. A spokesperson for the Eagle police helicopter said the crew had lasers pointed at them “all the time. It happens fairly often and it’s a real risk to the crew.”

Note: The FAA reports the 2011 total as 3,592. This is because the last entry in the FAA’s laser incident spreadsheet is on line 3,592. However, the spreadsheet headings are on line 1, so the actual number of 2011 incidents is 3,591 -- the number we use below.
What is an FAA-reported “laser incident”?: This is defined as an aircraft pilot seeing one or more laser beams during flight. A mid-2011 study by Rockwell Laser Industries of 6,903 incidents reported to the U.S. Federal Aviation Administration found that in 27% of incidents, beams entered the cockpit (passed through the windscreen). For example, in 2011, there were 3,591 incidents of which approximately 970 (27%) involved beams in the cockpit.
PowerPoint version available: A set of slides, presented to the SAE G10 aviation safety committee on Jan. 31, 2012, is available on the Files and Downloads page.
Yearly ComparisonHere are the number of incidents reported to FAA in recent years:
- 2011: 3,591 incidents (9.8 per night)
- 2010: 2,836 incidents (7.7 per night)
- 2009: 1,527 incidents (4.2 per night)
- 2008: 949 incidents (2.6 per night)
- 2007: 639 incidents (1.8 per night)
- 2006: 384 incidents (1.1 per night)
- 2005: 283 incidents (0.78 per night)
- 2004: 46 incidents (0.13 per night) involving an unknown number of aircraft Note: FAA mandated that pilots report incidents using Advisory Circular 70-2, beginning January 19 2005. Before this date, pilot reporting was voluntary.
This is a total of approximately 10,201 incidents reported to FAA, from 2004 through the end of 2011.
Adverse EffectsIn 55 of the 3,591 laser/aircraft incidents (1.5%), a pilot or aircraft occupant reported a temporary adverse visual effect such as flashblindness, afterimage, blurry vision, eye irritation and/or headache. None of these effects was classified as a recordable injury by FAA medical experts.
In these 55 incidents…
- … there were 31 reports of pain or discomfort in the eyes or elsewhere (e.g., headache).
- … there were 31 reports of vision impairment such as afterimages (10) and blurry vision (7).
- … seven persons sought medical treatment after the laser exposure.
- … one person was grounded temporarily.
- … three flights were affected: in two cases, the pilot turned control over to the co-pilot; in one case the pilot felt he had to land immediately.
Rate of increase, by yearWhile laser incidents continue to increase, during 2011 the rate of increase slowed significantly.
The rate of increase dropped 59% in 2011 (from 86.4% to 27%). If there is another 59% drop in 2012, (dashed line), then there would be a decrease in laser incidents for the first time, from 3,591 incidents in 2011 to 2,836 incidents projected for 2012.
“There are lasers used to hit satellites, it’s called dazzling, and it’s a show of force. There are a handful of countries that can do it. China dazzles U.S. and French satellites in low earth orbit not often, but regularly. What if a laser hits them, maybe lingers too long? A show of force can actually damage the satellite, knocks out some sensitive equipment. If that happens, and it’s from China, is that an act of war? What do you do? Political leaders have to be briefed on this. They have to make an effort to avoid escalation.”
From an interview in the Santa Barbara Independent conducted by Kevin Zambrano
The majority of South African incidents occurred in Cape Town, with other reports at OR Tambo, Wonderboom in Pretoria, and Lanseria International. In an incident in Lanseria, “two pilots were blinded so badly that after landing they couldn’t see the man who signaled where to park the plane” according to News24.com.
There were no persons arrested during 2011 for aiming a laser at aircraft. Over all years, there have only been two incidents resulting in arrests (as of January 11 2012):
- Around January 7-8 2012, three persons were arrested for pointing green laser beams at helicopters using the Bloemfontein civil and Air Force airports.
- During the 2010 World Cup, a man temporarily blinded a helicopter pilot in Durban
A Civil Aviation Authority spokesperson said “It is a serious hazard to point laser lights at aircraft.” The maximum penalty for an offense is a “hefty fine and up to 30 years in jail.”
The general manager of the Air Line Pilots Association of South Africa said ALPA-SA members were reporting increasing numbers of incidents where “sudden and intense bursts of light [are] deliberately shone at aircraft…”
From The New Age and DefenceWeb
Commentary from LaserPointerSafety.com: The figure of 70 incidents reported to ATNS in 2011 is probably low. A May 5 2011 news story quoted ALPA-SA as saying they receive between 10 and 12 complaints from pilots every week. That would result in 520 to 624 laser illuminations per year. Also, the 70-incident figure may be a misunderstanding or misquote. A news story from March 2011 quotes ALPA-SA as saying there were 70 incidents in the 10 months from April 1 2010 through February 28 2011; see News24.com.
The answer first noted that laser weapons are large. An anti-missile laser required a Boeing 747, the Navy set fire to a boat with a destroyer-mounted laser, and a dazzler-type laser called the PHaSR is as portable “as a bag of cement.”
Then, Straight Dope purchased a 1 watt blue handheld laser (the same or similar to the Wicked Lasers Spyder III Arctic). They aimed it at room temperature pork chops and bacon. From one foot away, it took 27 seconds of continuous exposure before smoke appeared. Even with matches, it took 11 seconds to light a match from one foot away, and 15 seconds from 32 feet away.
The January 6 2012 column concluded that handheld laser ray guns are not practical: “…the likelihood that this laser would actually change somebody’s mind (other than via intimidation alone) is virtually nil…. no bad guy is going to sit still while you fry him.”
Story and photos are at the Straight Dope website. The column was also printed in the Washington City Paper.
UPDATE: In comments at the Washington City Paper, “dave b” noted that exposure to skin isn’t necessarily the important factor: “The key is to get the laser into someone’s eye.”
KABC quoted the Glendora regional police helicopter tactical flight officer who was illuminated as saying “The laser could cause [eye] damage, and there’s a potential for the helicopter to crash.” The report said he and a pilot were recently trained by the FBI in how to handle a laser attack and how to track down a suspect.
Laser incidents are rising both nationwide and at local airport Los Angeles International (LAX), stated the report. It concluded by reminding the public that “any offense jeopardizes the safety of everyone.”
Figures for 2010 showed about 100 laser pen attacks on flights taking off or landing at the Yeadon-based airport. Figures from January 2011 through October 2011 showed 80 such attacks, indicating that the 2011 total would be similar to 2010.
A CAA spokesperson said laser pen misuse in Britain was not letting up in 2011: “The people who are carrying out these attacks are either still ignorant of the dangers high-powered lasers present to the safe operation of an aircraft, or they simply do not care.”
Mulholland said “a blanket ban on laser pointers is not the way forward because of the effect it would have on legitimate users. Something does, however, need to be done to address this serious ongoing issue.”

For the military laser enthusiast, the catalog contains a number of other laser devices such as the AN/PEQ-14 Integrated Laser White Light Pointer (actually a white flashlight plus a visible and an invisible laser):
From the Program Executive Officer Soldier Portfolio FY2012 catalog. The LA-8/P is on printed pages 138-139, electronic pages 146-147. Originally found via GovWin.
Commentary from LaserPointerSafety.com: Although the LA-8/P Aircrew Laser Pointer does not emit a visible beam, it would be easy to make a visible version so that aircrews could “fire back” at persons on the ground aiming laser pointers at them. Whether this is a wise idea is another matter.
The tower manager, Fred Hanson, was quoted as saying he would like to make lasers illegal because “it just totally changes the light effect in the airplane.” The president of the New Zealand Air Line Pilots’ Association also called for restrictions such as licensing, and having to have a reason for possession: “They do have the potential to wreak a lot of damage.”
A spokeswoman for Air New Zealand said the airline was concerned, and they support prosecution. New Zealand law calls for up to 12 months in prison or a fine of up to $10,000 for interfering with an aircraft. In a current case, two Auckland men are being prosecuted for aiming a laser at a police helicopter.

The news story points out that laser pointers can cause permanent vision damage. In addition, the story says the laser is sold “without a filter,” probably meaning without an infrared (IR) filter. IR light can damage the retina -- like visible light -- but also could damage the cornea.
Cockpit view of the ABL shooting down a missile on Feb. 11 2010. Video is here.
A key reason for the ABL shutdown was the cost of the project versus the projected military returns. Another reason is that the Missile Defense Agency is looking to a new generation of laser systems with “much denser capacity or greater power lasers in smaller packages and operating at much higher altitudes.” Unmanned aerial vehicles would be an ideal platform. The MDA’s director said antimissile drones using solid-state lasers could be a reality by 2020.
From Aviation Week. An analysis of laser weapons is at Strategy Page.
Commentary from LaserPointerSafety.com: We included this story because people sometimes wonder if lasers aimed from the ground can damage an aircraft’s airframe. The short answer is “no”. It would take a system similar to the $5 billion ABL. However, the Missile Defense Agency is now indicating that military-developed solid-state lasers may be able to cause enough damage to down a missile -- or aircraft -- within this decade (the 2010s).
While it is unlikely that non-state groups could deploy such a device, it is more of a possibility than independently developing an ABL-like COIL gas laser. For the foreseeable future, the threat to aircraft remains the visual impairment caused by bright laser light, and to a lesser degree, the possibility of causing retinal lesion eye injuries.

It is unclear what effect the FDA’s import restrictions have on supplies. For example, the well-known company Wicked Lasers is listed multiple times as being banned from importing “All laser products and all products containing lasers.” However, a company representative on December 22 said that Wicked does ship to the U.S. and there should be “no issues getting a laser into the U.S.”

Concept of the rifle, from the Daily Mail
The developer is Photonic Security Systems, which also markets the rifle as a pirate deterrent. The Telegraph says that similar devices have been used in Afghanistan by NATO-led International Security Assistance Force troops.
PSS managing director Paul Kerr told the International Business Times "The very purpose of this technology is to be non-damaging … If someone is prepared to just stand there and stare down the barrel at this, which would be incredibly uncomfortable, then they are definitely a threat.” He said that he has often been exposed to the laser: "The quality and safety of the device is paramount and I know that first hand because I have been the guinea pig many times. I know what it is like and I know how effective it can be."
Author and activist Cory Doctorow points out that “the UK is a signatory on the Protocol on Blinding Laser Weapons … this weapon wouldn’t run afoul of international law if it (merely) reduced your vision to the point where you were impaired but not legally blind, permanently.” Doctorow also says “Twitter wags are already predicting a resurgence of mirrorshades [reflective sunglasses] among protesters.”

A spokesperson noted that several of the arrests involved young people. He said, “We’re hoping parents will see this message so they can remind their children, if they have access to laser pens, not to use them irresponsibly.”
According to the news story, the maximum penalty for recklessly or negligently acting in a manner likely to endanger an aircraft is a fine up to £5,000, and/or five years imprisonment.

A promotional photo demonstrating the concept of the PinPoint Focus Assist
The manufacturer says the PinPoint complies with U.S. FDA safety regulations. It is said to be a Class 2 green DPSS diode with output power less than 1 milliwatt. The focus range is from 2.5ft/7.5m to 131ft/40m; the aiming range is 700ft/210m in low-light and “further in darkness”.
At their website, DeluxGear has an admirable list of safety warnings which include:
- Don’t aim at a person’s eyes. This can cause “temporary vision dysfunction such as flash blindness, disorientation or glare. This can be particularly dangerous if the exposed person is engaged in a vision-critical activity such as driving or other means of transportation.”
- Don’t aim it at a person without notifying them in advance.
- Don’t aim at a law enforcement officer as this is illegal in many jurisdictions.
- Never aim at vehicles including aircraft.
- Don’t allow a minor to use unsupervised. In some jurisdictions it is illegal for a minor to purchase or use a laser product
Incidentally, the beam on/off function is separate from the camera. This means the beam does NOT come on when the shutter button is pressed, but instead is controlled by a separate switch on the PinPoint.

Could a UFO with green lights have caused this crack?
It follows a report to the Halstead Gazette and a UFO website that a resident saw green lights rotating above her in Nether Court on Friday and left a large crack in the ground.
The frightened woman's daughter, who would only be identified as Nel, called Essex Police after the 7pm incident to check if it was the force helicopter. A police spokesman said it was not the helicopter but could have been laser pens.
But Nel is adamant it was not laser pens, and has since carried out internet research suggesting similar beams have been seen in diverse places such as Cornwall, Mexico, Nova Scotia and China.
From the Halstead Gazette on October 28 2011. Also, see this post at UK UFO Sightings; scroll down for the comment from Nel.
From The Independent and the Daily Mail
Speakers generally agreed on the nature and scope of lasers as a threat to air safety. They also offered similar solutions, including educating the public to not misuse lasers, prosecuting those who do, training pilots on how to "recognize and recover" from incidents, increasing the number of reports from pilots and the public, and restricting laser pointer availability.
The ALPA conference made news primarily for the announcement of a new FAA web page, which can be reached via www.faa.gov/go/laserinfo. FAA Administrator Randy Babbitt told the ALPA attendees that the web page -- erroneously described as a "website" in many media accounts -- would centralize the agency's information on laser/aviation safety. The page includes email addresses where pilots, air traffic control and the public can report laser incidents (see separate story about the FAA web page).
Babbitt also said that the FAA currently has filed 18 civil cases against individuals who aimed lasers at aircraft. There is a maximum $11,000 fine in each case.
Other speakers gave updates and information in their areas of expertise. Read More...

The action was taken because laser attacks are on the rise: six in 2009, 11 in 2010 and 16 to mid-October in 2011.
The sale of strong laser pointers was banned in Switzerland in May. The Federal Health Office is currently reviewing the possibility of banning their possession and use. Checks carried out by the Federal Office of Metrology this year showed that more than 95 per cent of the pointers tested were stronger than the permitted limit.

The bill stipulates that hooligans whose actions have threatened transport safety will be fined 80,000 rubles ($2,580) or sentenced to up to three years in prison. People caught with pointing lasers at aircraft will get 7-year jail terms. Hooligans whose actions have led to the death of people or other grave consequences will get up 10 years in jail.
The bill also lowers the age of persons who could be punished for laser hooliganism from 16 to 14 years.
Only five cases of laser attacks were registered in the country in 2010, but in 2011 the number jumped to more than 30. One suspect was caught in Moscow this June, and another in the southern Russian republic of Chechnya a month later and received little or no punishment. A 17-year-old suspect was told he would "face very strict measures" if a similar incident occurs again, the Chechen Interior Ministry said on its website.

The laser pointer is imprinted with the slogan “Nuclear Energy for All, Nuclear Weapon for None” at the top, and “I.R. of Iran, Uranium” at the bottom. The design is based on the Iranian IR-1 centrifuge, which in turn is based on the Pakistani 1 (P-1).
Iranian President Mahmoud Ahmadinejad walks past rows of IR-1 nuclear enrichment centrifuges during a tour of Natanz on April 8 2008.
Iran’s nuclear program has been heavily scrutinized by Western countries, with several United Nations resolutions imposing sanctions on the country. It is widely believed that the U.S. and Israel may have developed and distributed the Stuxnet virus in order to cripple Iranian centrifuges. Approximately 1000 IR-1 centrifuges were damaged, out of about 10,000 total centrifuges at the Natanz uranium enrichment facility.

The company also introduced the Laser Eye Protection Program training course. It is intended to “teach aircrew members the capabilities, limitations and preventative measures required to respond to a laser strike.” The cost is $125; the course takes about an hour and has a test at the end.

Each of the four headlights uses three blue lasers. The lasers are directed by mirrors onto a lens containing yellow phosphorus. This re-emits white light onto a larger mirror that reflects it out the headlight glass onto the road.
Two of the four laser headlights are shown here. The resulting white light beam is emitted toward the upper left of the photo.
The system is 1000 times brighter than LED headlights, uses half the power, lasts just as long (10,000 hours) and allows more flexible designs. BMW noted that light emitted from the headlights is not laser light, and is safe to stare into. In case of an accident, the headlights are powered down so no laser light could escape.
[Note from LaserPointerSafety.com: It is likely that the laser diodes in the headlight are the same type used in Casio’s Green Slim projectors and the Wicked Laser Spyder III Arctic handheld laser. These are relatively inexpensive -- less than $30 each in quantity -- and produce a nominal 1 watt of light.]

In retaliation, Teachout said the three-pilot Civil Air Patrol would not provide help to Horry County (where Mytle Beach is located) for certain calls including offshore missing persons and forest fires. According to the Sun News, Teachout said “I support Horry County but if they don’t have [the pilots’] backs then no thanks. We don’t need to be here.”Read More...
In 2008, there were 1,048 European incidents.
A Eurocontrol safety expert said “Preventing and mitigating the current problem requires a harmonized approach throughout Europe. We need the full involvement of regulators, judicial authorities, police, airlines and their associations, air navigation service providers, laser manufacturers who must understand how serious the problem is, as well as research institutes.”
Most European countries do not have specific laws against aiming lasers at aircraft. Eurocontrol stated they should be subject to the same restrictions as firearms, covering the purchase, transportation and use of lasers.
German politician Volker Kauder said that high-powered lasers should be treated as weapons under the Geman Arms Act.

The City Council is considering a local law to make malicious shining of lasers a Class 1 misdemeanor (up to a year in jail and a $2500 fine). According to PilotOnline.com, in 1998 Virginia Beach “was one of the first in the nation to make it a crime to shine lasers at police officers or into people’s eyes.”
The city is also planing an educational campaign to inform people about the law and laser dangers.
Commenter “Lost_Sailor” said there already is a Virginia state code, 5.1-22, “Interference with operation of aircraft,” to address the problem. He linked to a 2002 Virginia Court of Appeals case upholding the conviction of a man for using a “million candlelight spotlight” to illuminate a police helicopter. The man unsuccessfully argued that he had no intent to interfere with the helicopter; he wanted to view its registration number for a noise complaint. The man also unsuccessfully argued that his spotlight did not interfere with the operation of the aircraft.
From PilotOnline.com. The comment by Lost_Sailor was submitted on Thursday, 10/06/2011 at 6:40 pm.
The video highlights Justin Stouder, a St. Louis-area resident who was arrested in April 2010 for aiming at a police helicopter. He apologized at a news conference in July 2011 intended to publicize the illegality and hazards of lasers aimed at aircraft.
The FBI also released video excerpts of the Stouder laser incident and his subsequent identification by the helicopter and arrest. The incident/arrest video was about 10 times as popular on YouTube, with over 225,000 views:

A news report on WPRI said Whitehouse introduced this as a standalone measure. In February 2011 Whitehouse had proposed the same provisions as Amendment 8 to S. 223, the FAA Air Transportation Modernization and Safety Improvement Act which passed the Senate February 17 2011. Because House action on FAA funding was held up, Whitehouse decided to re-introduce the measure as its own bill.
The House version is H.R. 386 introduced January 20 2011 by Rep. Daniel Lungren, Republican of California. The House bill also provides a penalty of a fine and/or up to five years in prison. It was passed by the full House on February 28 2011.
It is likely that S. 1608 will successfully pass in the Senate Judiciary Committee and the full Senate. If the bill is identical to H.R. 386, then the legislation would be sent to the President for his approval and signature. If the bill differs from H.R. 386 -- for example, if amendments are added -- then a House/Senate reconciliation committee would meet to work out the differences, in advance of sending a single piece of legislation to the President.
From WPRI.com. S. 1608 can be tracked on GovTrack.us; as of September 25 2011, the text of the bill has not yet been posted.
92 laser sights and 74 automatic machine guns were ordered between Sept. 2008 and January 2010 on Lake County letterhead and purchase orders. The officers paid for the products with personal funds. The amount earned from Internet resales was not stated, although the three officers were also indicted for understating their personal income by a total of $387,000.
The laser products came from Insight Technology Inc. and Laser Devices Inc. The 92 restricted laser sights were purchased for approximately $1000 to $1400 each and were sold on eBay for around $2800 to $4200 each. A special agent of the U.S. Food and Drug Administration (which regulates laser devices) made an undercover purchase as part of the evidence-gathering process in the case. Read More...
Due to the potential for catastrophic injuries from lasers, the UAW bargaining team pushed hard to expedite safety training in this growing field. Within 30 days of ratification, the UAW-GM Health and Safety Training Department will schedule a train-the-trainer (T3) Laser Safety Awareness Training course to be taught at the CHR [UAW-GM Center for Human Resources].

The city has received more than 100 complaints about laser misuse. A spokesperson for the city said “We've had many complaints this past summer about people, mostly people under 18, shining the green laser into the condominiums, into hotel rooms … at people on the beach, at animals, and even at turtles. When they were hatching, they would shine them on the small turtles and lead them away from the ocean.”
(Note: the city of North Myrtle Beach is separate from its neighbor Myrtle Beach which has enacted restrictions on pointers.)

The Swiss government banned the sale of “powerful laser pointers” in May 2011. According to World Radio Switzerland, the country is considering a ban on owning such pointers.
From World Radio Switzerland
For adults, the proposal would ban use in public such as beaches, parks or streets. It would be illegal to aim lasers at a person, animal or vehicle. Violation would be a misdemeanor, with a penalty of up to a $500 fine and one month in jail. Read More...
LaserPointerSafety.com’s analysis shows it is a distraction hazard to pilots up to 20 miles from the laser source. Read More...
The eyewear, made by NoiR, significantly reduces laser light, without adversely affecting pilot vision of cockpit instruments or airport lights. Because some laser light is transmitted, pilots and flight officers will still be able to track the source of a laser illumination.
The decision to purchase the glasses was made because of recent laser incidents in the St. Louis area. A spokesperson said the eyewear is “another tool to keep us in the air.”
The analysis was done by Rockwell Laser Industries (RLI). They examined 6,903 incidents in FAA’s database, dating from 2004 to mid-March 2011.The cockpit was illuminated only in about 1,875 incidents (27%). Of these, the exposure appeared intentional in about 350 incidents (19% of the cockpit illuminations; 5% of all illuminations). “Intentional” was defined as multiple beam exposures or the beam tracking the aircraft.
There were about 100 incidents (1.5% of all incidents) reported eye effects or injuries to the eyes. (A separate analysis by LaserPointerSafety.com shows that the vast majority of eye effect/injury reports are of minor, temporary effects. There are a few claims of eye injuries, and a very few confirmed claims of retinal injury.)
The RLI analysis was done by Kevin Donnelly, and was supervised and presented in August 2011 by RLI president Bill Ertle. Rockwell Laser Industries is a pioneer in providing services and products related to lasers and laser safety.
Black Hawk and Chinook helicopters have been testing a acoustic detection system called “Helicopter Alert and Threat Termination”, or HALTT. This uses microphones to detect the sound of a bullet or RPG. Delays in the sound reaching the microphones enables them to determine the sound’s location. A similar truck-mounted system is already in use. It can automatically swivel and fire a gun in the direction of the sound.
For helicopters, HALTT can be combined with guns and/or lasers. Infrared lasers help confuse missile guidance systems, while visible lasers would dazzle and flashblind anyone aiming at the helicopter. An engineer said the principle is to “make it impossible for a human to observe your aircraft … by creating a distracting light source. That has been done in the past and is a proven technology…”. The HALTT/laser countermeasure system could be in use by 2017.
The military already uses laser dazzlers at checkpoints, to warn approaching vehicles and to cause glare on anyone taking aim at soldiers.
From Wired and Defense Tech. A video of how the IR system would work against a missile is at YouTube.
Among those attending the meeting were representatives from the Ministry of Internal Affairs, committees of the city, flight crews and air traffic controllers.

Senate Bill 2888 was introduced by Antonio "Sonny" Trillanes IV, as a result of laser illuminations on aircraft at Manila International Airport.
The Manila Bulletin reports the bill's provisions as follows:
- “Any person who uses a laser pointer, pen or similar device to distract, annoy or attack another person” faces prison terms of from three to six months, or a fine ranging from P10,000 to P100,000.
- When the attack results to damage or destruction of property, the penalty shall be three times the value of the damaged property and imprisonment of six months to one year.
- When the person attacked suffers from temporary or permanent disability or injury of any kind, the penalty shall be imprisonment from one year to three years.
- When the person attacked is operating a motor vehicle, the penalty shall be four years to eight years.
- When the person is operating an airplane or helicopter or a ship at sea, the penalty will be imprisonment ranging from eight to ten years.
Saulnier told police he had the pointer because he was an amateur astronomer. The Calgary representatives of the RASC said Saulnier was “not an RASC member, nor [was he] known to us.” They pointed out that responsible amateur astronomers would use lasers only on astronomical targets on clear nights when others are present: “There is no legitimate solo use of pointing a laser pointer into the sky that we can think of.”

LIA did not give specific recommendations to avoid eye injuries, other than individuals being cautious. They did note that “[t]here is an active debate about what should be done. Is the solution education, regulation or prohibition for this type of hand-held laser device?…. Until the time that these lasers are statutorily banned, regulated through licensing or are widely recognized as a hazard, many more injuries will occur. The public should take note of these dangers immediately and keep these high-power, hand-held devices away from children and the untrained user.”
