A comprehensive resource for safe and responsible laser use
Two frames from the South Australia Police helicopter. In the first frame the laser beam is aimed to the left of the camera. In the second frame the beam is aimed directly at the camera lens. The human eye would have a similar effect, first seeing the beam then being dazzled and flashblinded by the bright direct light.
According to the Herald Sun, the laser was "2000 times more powerful than the legal limit", which would make it 2000 milliwatts or 2 watts.
The perpetrator was found to be Mark Andrew Golka, 49, who lived in the Adelaide suburb of Woodcroft. He was said to have been drinking alcohol and taking prescription pain medication when he aimed the laser. At sentencing, the judge told Golka "…that is no excuse to having committed these offences."
Golka was sentenced to 15 months in prison, suspended. He signed a two-year good behavior bond, will be supervised for 18 months, and will perform 80 hours of community service.
After the sentencing, his lawyer said Golka was sorry for what he had done.

The helicopter crew directed ground officers to a home where the 22-year-old was arrested. He was charged with causing fear or alarm with a laser or light to people in conveyances or others. The man faces a prison term of up to seven years and a fine of up to AUS $36,000 (USD $26,600).

CHP pilot Jan Sears was directly illuminated by the blue laser beam. He later described the effect: "So it's pitch black and we're flying and all of a sudden it's like the sun just came out. It took me a minute to get my bearings…." Sears was able to control the aircraft by activating the autopilot. The CHP flight officer directed deputies on the ground to the suspect's location.
He was identified as Christopher Larsen, 33. He was charged with two state felonies for discharging a laser and aiming a laser at an aircraft, and may also be charged with a federal felony.
Sears said Larsen was "using a laser that's illegal, much more expensive and highly powerful." He noted that "In a week we are lased once maybe twice; sometimes we catch them, sometimes we don't."
A laser similar in design to the one Larson was found with
Sears told NBC Bay Area that he was "still having residual effects with my left eye. I feel that something has happened." He said he had experience with green lasers before, but "this was a blue laser. It was the worst type to get involved with." Protective eyewear was on board, but it was intended to reduce green light, not blue.

Commentary from LaserPointerSafety.com: Most lasing incidents involve green light, so glasses that reduce the intensity of green light can be useful. Glasses are available which reduce green and blue — and even green, blue and red. However, the more wavelengths of light that the glasses attenuate, the more overall light is also dimmed. Plus this can make it more difficult to differentiate colors on the aircraft instrument panel. More information is on the page about laser glare protection eyewear.
On July 18 2019, the helicopter was searching near Stephen Reid's home when the man pointed the laser at it. His location was identified, and Reid threw the laser into his back yard when illuminated by the helicopter spotlight.
Officers on the ground had to threaten to force their way into Reid's home before he opened the door. A blue and a green laser pen were found by a canine unit. Reid admitted the lasers were his.
In court in January 2020, Reid's attorney said Reid was "plagued by police helicopters searching for individuals…. Something got into his head and he utilized this laser pen to cause what could have been a catastrophe."
On January 29 2020, the judge gave Reid a four-month sentence suspended for 18 months, plus he had to complete a 60-day rehabilitation program.
The judge said "Any distraction and that helicopter is crashing into an urban area with devastating consequences. You were irritated, frustrated and annoyed at what they were doing interrupting your audiobook and it’s clear you were not thinking about the consequences of your behaviour. By the finest margin I can imagine I can suspend this sentence. You’ve caught me on a good day."

The laser pointer was confiscated and the unnamed man was charged with “causing fear or alarm to the driver or pilot of a conveyance or others.” He will appear in court later in July 2018.
According to a police Facebook post, “the officers were temporarily blinded by the laser, but there were no serious injuries.” The source of the laser was traced to a vehicle on Manassas Gap Court in Centreville.
Carlos Zapata Rivero was charged with shining a light/laser pointer at an aircraft, which is a Class 1 misdemeanor.

Zipf had previously been convicted in 2011, of pointing a blue laser at a Phoenix police helicopter. It is not known what fine or sentence, if any, came out of the 2011 conviction.
In June 2014 he pleaded guilty to one count of aiming a laser pointer at an aircraft, a felony in the U.S. since February 2012. In addition to the prison sentence, Zipf also must undergo mental health and substance abuse treatment. He has until December 30 2014 to report to prison.
From KLAS-TV and a press release from the U.S. Attorney’s Office for the District of Nevada. LaserPointerSafety previously reported on Zipf’s February 2014 indictment, and details of the lasing incidents, in this story.
On December 1 2013, Kristian Larsen aimed a blue laser “like a light sabre” from his home in central Auckland towards the aircraft which was taking off from the police helicopter base at Mechanics Bay. The laser beam led police to Larsen’s location, where he was arrested.
The 44-year-old man is charged with endangering transport.
Police said similar lasers are shown on YouTube videos as cutting through plastic and setting fire to objects. An investigation is ongoing.

US: UPDATED - Las Vegas area man, previously convicted of aiming lasers at helicopters, does it again six times
James David Zipf had been convicted in Phoenix, Arizona in 2011 for aiming a blue laser at police helicopters. In May 2013 he moved to Henderson, Nevada, 12 miles from Las Vegas.
The indictment stated that Zipf aimed a laser at Las Vegas Metro Police helicopters six times between January 31 and February 12 2014. In one of the attacks, the pilot was so disoriented that he landed the aircraft and ended his shift.
At a detention hearing, Zipf was ordered to remain in jail. The judge said he had endangered the helicopter crews, was a threat to the community, was not truthful to federal agents, and was using drugs.
Zipf faces up to five years in prison and up to $250,000 in fines for each of the six counts.

UPDATED - September 24 2014: Zipf was sentenced to two years in prison. He also must undergo mental health and substance abuse treatment. A news reported noted that one of the flight officers in a February 3 2014 incident experienced a severe headache. From KLAS-TV
Michael Rademacher, a traveling maintenance man, had purchased the blue laser and used it to etch his initials on his work tools. On the night of March 21 2013, he was bored and decided to aim it at the police helicopter. One pilot said it was the brightest he had seen pointed at him. After regaining their bearings, the pilots identified the source of the beam and notified ground officers. Rademacher initially said he was not involved but he confessed after officers armed with a search warrant found his laser.
In September 2013, Rademacher pleaded guilty to one felony count of possession of criminal tools. As part of the plea bargain, the more serious charge of interfering with the operation of an aircraft was dropped.
If Rademacher violates probation, he will be imprisoned for 12 months. Rademacher also lost his job as a maintenance man due to his arrest and plea.

One neighbor interviewed said a man had aimed a “bright blue light” at her children. A woman in the police-targeted house said her son-in-law was contacted by police but could not say if he was charged. She did say that police said they would turn the case over to the FBI.
The house is located about 21 miles southwest of Denver International Airport.
According to the FAA, there were 32 Denver-area laser/aircraft incidents during 2012, compared with 41 from January 1 to August 15 2013.

Nicholls’ attorney said he did not mean to intentionally endanger the aircraft. He pleaded guilty to one count of recklessly or negligently acting in a manner likely to endanger an aircraft or people in an aircraft.
Six month sentence for Alexander Nicholls
The six month sentence was intended as a “deterrent” because “the result could well have been catastrophic,” according to the chair of the bench.
Statistics show that from January through mid-July 2012, there were 31 reported laser incidents in Avon and Somerset, compared with 26 for the same period last year.
