A comprehensive resource for safe and responsible laser use
While both the U.S. and the U.K. have laws with penalties up to five years in jail, in the States jail sentences have been imposed while fines are the norm in Britain. The U.S. also has a centralized national reporting system, which the British officials seek to emulate.
Mark Callaghan, an NPT inspector for Sussex Police, told the Express about a case in April 2014 where a laser beam was aimed at an Airbus A319 from a Travelodge near Gatwick Airport. The pilots reported that “The green laser was extremely aggressive and we suffered three or four two-second attacks directly into the cockpit causing blotchy vision, squinting, broken concentration, sore eyes.” The perpetrators were not caught.
Callaghan noted “We can find out who was in the rooms but we have no power to conduct any searches and even if there were lasers there what evidence is there to say they did it? We would like some preventative legislation. The US have got it nailed on how they deal with this.”

In the ten weeks prior to September 26 2014, there were seven incidents of lasers being pointed at aircraft; five of these led to arrests.
News reports did not directly link the misuse to the man arrested with the 107 laser pens. It also is not known if the investigation that led to the seizure was started in response to the aircraft incidents, or was separately initiated. All flights landed safely.
One of the seized pens was said to be 650 times more powerful than normal. Given that U.K. regulations prohibit laser pointers above 1 mW, the pen was likely 650 milliwatts. This is Class 4, the most hazardous laser classification, as the beam can cause eye and even skin burns.
From the Daily Echo
The first draft of the April 2014 law called for a Class Five felony to “knowingly or intentionally” aim a laser towards an aircraft. But there was concern among legislators that juveniles could end up with a felony record. The bill passed once the penalty was reduced to a Class One misdemeanor.
In a September 22 2014 story, reporter Emilie Eaton recounted Arizona’s experience. FAA-reported incidents in the state rose from 138 in 2010, to 202 in 2013. One police pilot interviewed said that he had been hit by lasers over 100 times, during a 22 year career. The pilot, Chris Potter, said he had permanent damage from a laser strike: “It literally felt like I got punched in my eye and there was a piece of debris, like a piece of glass in my eye.”
Another pilot quoted, Pima County Sheriff’s Department deputy Chris Janes, said he has has between 12 and 24 laser strikes from 2007 to 2014: “I have not received any eye damage. But I’ve had headaches afterward. I’ve had eye discomfort for several days afterward.”

The newspaper also reported that in the 12 months between October 2012 and September 2013, there were 31 reports of aircraft being illuminated as they approached Gatwick Airport, 30 miles south of London.
Laser strikes have also increased on rescue helicopters flying out of Redhill Aerodrome, Surrey, a few miles north of Gatwick. A tactical flight officer was quoted as saying “I've had to break away from a task because of being lasered and it's not because we're trying to catch a bad guy, it's because we're trying to find people potentially in danger.... There are certain elements of society that might be trying to harm us or put us off being in a certain location.”
Police inspector Mark Callaghan told the Mirror that there have been a number of jail terms for perpetrators, but that "Hand-held lasers are easily obtained over the internet or from market stalls and street vendors abroad. The warning labels on these are misleading and they are more powerful than advertised."
From the Surrey Mirror
In addition, if the laser pointing results in serious bodily harm to a human being (defined as “an injury that requires hospitalization, long-term treatment, or causes permanent or mutilating injuries”), the violation becomes a felony.
As of August 14 2014, it is not known if the act has been signed by the Governor, and thus whether it has become an official law. [Usually, such laws are signed by the executive. However, in October 2013, New Jersey Governor Chris Christie vetoed a law, passed by the legislature, that would have banned the sale of laser pointers over 1 milliwatt.]

After tests in mid-2013, the Basil Justice and Security Department purchased 1,000 pairs of laser protective eyewear, at 200 Swiss Francs each (USD $224).
All Basel police officers and rescue emergency vehicles are equipped with the glasses, as of December 2013. Other Swiss cantons are in the testing phase.
The Basel anti-laser glasses are demonstrated in this frame from a SRF video.

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.
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.

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.
UPDATE 2 - May 1 2014: The bill was eventually amended to make the act of aiming at an aircraft a Class 1 misdemeanor. The act became an assault if the pilot was unable to safely operate the aircraft or if anyone onboard suffered a serious physical injury. The amended version passed both legislative bodies and was sent to Governor Jan Brewer, who signed it on April 30 2014. From the Arizona State Legislature legislative history of HB2164.
UPDATE 3 - September 23 2014: The Arizona Police Association and other law enforcement groups want to increase the penalty to a felony. They hope to introduce a measure when the legislature re-convenes in January 2015.
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.
From KVOA News
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).
Since 2011, laser pointers above 5 milliwatts are prohibited in Switzerland. The Swiss Federal Office of Public Health is working on proposals to classify laser pointers as weapons and will present these by 2014.

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 local Coast Guard echoes the concerns. Twice in two weeks, search and rescue missions were ended prematurely because of lasers being aimed at helicopters. (See a report here.) Under Coast Guard regulations, after laser exposure the aircraft is grounded and the pilots are medically evaluated before being allowed to fly again.
The Coast Guard issued a letter asking the public to stop aiming at aircraft, and saying that they want to enforce South Carolina’s state law against lading aircraft. The letter is reprinted below (click the “Read More” link).

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”).
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%.

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.”

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...
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.”
Provincial Judge Paul Sully said the August 19 2009 incident was "not as serious” as the prosecutor described, since the pilot did not lose control, but instead was "momentarily blinded from viewing his instruments [and] was able to complete his orbits.” In addition, the judge noted that the pilot was familiar with the dangers of laser light.
Judge Sully also rejected the prosecution’s notion that the man should have culpability: “The offender had a momentary loss of common sense which resulted from his failure to recognize the high standard of care needed when handling a laser.” Read More...
