Concerned about laser pointers? Want them used safely?

Welcome to LaserPointerSafety.com. We are an independent resource for users, regulators, pilots, media and others concerned with handheld portable lasers.

While laser pens are useful and fun, they are all too often misused. This website has details such as…

New: 2017 laser illumination reports expected to be less than 2015 and 2016

As of June 30 2017, there have been 2,933 laser illumination incidents reported to the U.S. Federal Aviation Administration. This compares with 3,441 reports in 2016, and 2,692 reports in 2015 over the same Jan. 1 - June 30 time period.

Based on historical data from 2007 through 2016, LaserPointerSafety.com estimates that there will be around 7,200 reported incidents in 2017. This compares with 7,442 reports in all of 2016, and 7,703 reports in all of 2015.

Additional detail, plus two data charts, is in a story recently posted to the News/Statistics page.

Update October 2016: FDA wants to allow only sales of red laser pointers

On October 25 2016, the Food and Drug Administration proposed significant changes to U.S. federal laser pointer laws. Their intent is to designate all laser pointers that are not red as “defective.” This designation would prohibit U.S. sales of green, blue and other non-red pointers and would make it easier for FDA to control and seize imports of such lasers.

For a detailed description of the proposal, and FDA’s rationale behind this move, see our October 26 2016 news story or this even more detailed 10-page paper presented at the 2017 International Laser Safety Conference.

Learn from his mistake — don’t aim lasers at aircraft

A California man wrote a letter apologizing for aiming a laser at a sheriff’s helicopter. He describes how it ruined his life:
     I was convicted of one count of aiming a laser pointer at an aircraft and sentenced to 24 months in a federal penitentiary, then 36 more months of supervised release for a total of 60 months — five years — plus ordered to pay a special assessment fee of $10,000. I am very lucky the pilot was an expert and highly skilled at piloting the helicopter.

     I also want to educate anyone who owns a laser and might be inclined to use it the way I did: Learn from my mistake. I am now just getting out of prison. I have paid dearly, for I have lost my girlfriend, my dog, my home, my vehicle. Everything I owned, everything I have worked for 30 years of my life, is gone.

     For shining a laser at a helicopter for three seconds, I lost my entire life. I am now 54 years old and I have no one and nothing but the clothes I was given when I was released from prison.
More details on this unfortunate situation are in an in-depth December 2016 Ars Technica article by Cyrus Farivar, which is summarized here.

Eye hazard results

( ( 32.8 / [mrad] ) * ( sqrt ( 0.5 * [mw] ) ) / 3.16 )
At the ED50 distance, there is roughly a 50-50 chance that a fixed laser beam aimed into an unmoving eye under laboratory conditions will cause the smallest medically detectable change to the retina.

The ED50 distance is about 1/3 of the NOHD. The extra space between the ED50 distance and the NOHD gives an added “safety margin” or “reduction factor.” Beyond the NOHD, the laser light is considered unlikely to cause any eye injury.

Being exposed to laser light within the NOHD does NOT mean that a person will automatically receive an eye injury, or even is likely to have an injury. The NOHD is a “nominal” hazard distance, not an actual hazard distance. The closer the person is to the laser, the greater the chance of an injury, as shown by the colors above.

A special message for laser pointer users

There are far too many incidents where airplanes, helicopters, vehicles, athletes and ordinary citizens are harassed by laser pointer beams. It is annoying, at best. It can be unsafe if the beam gets in someone’s eye or if it causes a driver or pilot to be distracted or flashblinded. You personally can get arrested and even jailed.

Plus, laser incidents create a bad image and can lead to laser pointers being banned. This has happened in a number of areas. (In New South Wales, you can be fined for possessing a laser pointer, and you can go to jail for up to 14 years for a laser assault.) There are strong calls in Canada, the U.S., and the U.K. to restrict or ban lasers.

It is really simple: NEVER aim a laser beam at an aircraft, a vehicle, or towards strangers. In other words, DON’T ANNOY PEOPLE WITH THE LASER BEAM.
