A comprehensive resource for safe and responsible laser use
From late March to mid-June 2018, 450 fires caused by the aerial attacks burned about 7,500 acres of farmland and national parks, including 1,400 acres of wheat.
In response, the IDF has developed systems to locate the kites and balloons, either intercepting them or sending fire fighters to the landing locations. One interception technique uses a laser on a drone that in tests “has been successful in incinerating the incoming trajectory, neutralizing it and bringing it down.” It is expected to be deployed “soon” according to news stories in late June 2018.

It is not clear if these military incidents are included in the Civil Aviation Authority (CAA) statistics about laser illuminations of aircraft.
The Ministry of Defence figures, made public June 11 2018, were rounded to the nearest 10. The list below shows the reported military-related laser incidents in the UK, along with the CAA numbers for the UK and for overseas UK operators
2013 - 40 military, 1396 CAA UK home, 329 CAA UK overseas operators
2014 - 70 military, 1447 CAA UK home, 317 CAA UK overseas operators
2015 - 70 military, 1440 CAA UK home, 355 CAA UK overseas operators
2016 - 30 military, 1258 CAA UK home, 274 CAA UK overseas operators
2017 - 40 military, 989 CAA UK home, 243 CAA UK overseas operators
The information was released in response to a written parliamentary question submitted by former defence minister Kevan Jones, who said “New laws to deter those stupid enough to carry out these attacks might not be enough, and the Government should give police operating around air bases the resources needed to catch offenders.”

- An infrared (1535nm) laser rangefinder determines the distance to a person or object. The closer the distance, the lower the laser power output.
- Near-field detection shuts off laser emission if a person or object is too close to the laser output aperture.
- A 3-axis gyroscope detects motion. If the Glare Recoil is suddenly moved, the laser shuts off until stability is resumed and an accurate determination of the distance to a person or object can be re-established: “This prevents hazardous irradiance in situations where Glare Recoil is moving faster than the laser rangefinder can detect objects and dose power output. This results in the prevention of eye hazard danger caused by rapid movement of the device (example: flagging) or improper situational awareness of the operator.”
With these technologies, the laser detects objects or people in the proximity of the beam and then self-adjusts the power output to maintain eye safety. The Nominal Ocular Hazard Distance is said to be 0 meters; the range is 10 feet to 10 miles.
Suggested uses include urban patrolling, cordon and search, crowd control, clearing facilities and security checkpoints.
The Glare Recoil is about the size of a Walkman tape player at 5.5” x 3” x 2”. It can mount on a rifle or be handheld.

While the original draft RFP was published for comments on March 27 2018, the revised request takes on additional urgency after the Pentagon on May 3 2018 accused China of aiming lasers at aircraft flying from a U.S. airbase in Djibouti. According to the Pentagon, two pilots had minor, short-term injuries as a result. The next day, China denied using lasers against aircraft in Dijibouti, calling them “groundless accusations.”
The current provider of the Air Force’s laser protection is Teledyne Scientific & Imaging, which was awarded a $30.1 million contract in July 2016 for 11.805 Aircrew Laser Eye Protection (ALEP) Block 2 glasses. The May 2 2018 RFP is for Block 3 glasses and visors. and will provide protection both during the day and at night from laser light.
The RFP’s Requirements Matrix does not specify the exact wavelengths to be blocked. It does say that the night version must have at least 50% visibility (Photopic Luminous Transmittance) and at least 14% for day versions. The document also states:
The ALEP Block 3 will not impair visual performance to the extent that it interferes with safety of flight or mission completion. The device will be visually compatible with the following devices/activities:
- All USAF aircraft
- Joint Helmet Mounted Cueing System (JHMCS); Night Vision Goggles (NVG); Panoramic Night Vision Goggles (PNVG), Helmet Mounted Integrated Targeting (HMIT/HoBiT), and fielded/post- Milestone B visors and aircrew chemical warfare masks
- Canopies/windscreens, HUD, and color cockpit displays
- Detection, recognition, identification, and tracking of targets
- Ability to distinguish terrain colors and geographical features
- Cockpit interior lighting, external aircraft lights, and airfield lights
- Ability to read charts, maps, and other printed materials in the cockpit
- Ability to perform normal aircraft duties in cockpit

“We already had several such cases (a laser injury of the eye retina) in the State Border Guard Service and in the National Guard. We are now developing countermeasures. We do not fully understand what they use, but we are already working on the instructions what it could be. We will install the appropriate filters, devices, use appropriate glasses,” Avakov said.
He reported on four cases of the laser injury of border guards and national guardsmen.
“The use of such weapons is a barbarous situation. We will discuss it at the international level,” Avakov emphasized.

In an interview, Chief Warrant Officer Robert Williams discusses the hazards of laser interference with pilots. He recounts an episode in mid-July 2017 where he and a co-pilot were lased. They identified the source of the laser beam. Ground officers found that the perpetrator was a teenager. Williams said “We specifically requested that the cops not get the FBI involved. I don’t want any kids going to jail or getting felony charges on their record.”
He added, “When the cop showed up at the door and explained to the dad what was going on, the dad broke the kid’s laser there on the spot.”
The reluctance to report appears to stem from a 2009 lasing incident which was reported to the FBI. A 30-year-old man, Joshua Don Park, “on a whim” decided to aim a cat laser pointer at a Utah National Guard helicopter. Park told arresting officers that he was unaware the laser’s light could interfere with pilots’ operations. The Journal story says Park “faced up to five years in prison. [Another source says he faced up to 20 years.] Tragically, he committed suicide shortly before he could be sentenced.”
The story continues, “Since that sobering incident, no Utah National Guard pilots have reported lasing incidents to the FBI—but not for lack of occurrences. ‘My unit alone has had two incidents in the past three months,’ said Williams.”
From the South Valley Journal. More details about the original February 2009 lasing and September 2009 suicide are here.
The information was released to help reassure any residents who might see the beam. The Navy called the beam “eye-safe” and said the beam would be turned off if an aircraft or watercraft is within 300 meters.
The purpose of the test is to “evaluate the performance of a laser system at long range over water,” according to a spokesperson. The laser would be aimed from the source to a target as far as 13 miles away.
There was speculation that the laser was 150 kilowatts, based on an earlier speech by the vice chief of naval operations. However, the spokesperson said the June 27 test would not be using the 150 kW laser.

To help defend drones against laser light, a California company has developed a defensive laser to be mounted on the drone. When it detects a laser attack, it first analyzes the incoming beam’s power, wavelength, pulse frequency and source. It then uses its own laser to counter the incoming beam.
The exact method is secret. New Scientist speculates “…it may involve fooling the control system into thinking it is hitting its target despite the laser actually pointing a few metres to the side. A direct hit would have produced a big burst of reflected light, so a pulse sent back by an anti-laser laser could make it look like the original laser was on target.”
The company is Adsys Controls of Irvine, California; the anti-laser laser system is called Helios. According to the company, “Helios is a low SWaP [Space, Weight and Power], completely passive Counter Directed Energy Weapon system capable of nullifying the enemy’s DEW [Directed Energy Weapon]. Consisting of a small UAV-mounted sensor package, Helios provides full analysis of the incoming DEW beam including localization and intensity. With this information it passively jams the enemy, protecting the vehicle and the payload.”

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 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.
One of the four sensor packages to detect laser threats on U.S. military helicopters
Laser protection team leader Andy Mott was quoted as saying “Lasers of varying pulse width and wavelength are being developed every day. We protect against the known threats, and unknown ones. We develop protection for electronic sensors of the future, as well as the sighting systems of today.”

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).

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.”
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.

From a Teledyne Technologies press release
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.
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.
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.”
From the Telegraph, the Daily Mail, the International Business Times and BoingBoing. See related story on BAE Systems anti-pirate dazzler.
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.
