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.

The laser portion of the 21-page document is four paragraphs long. The analysis appears to be sourced primarily from news accounts and public documents.
The fourth paragraph, which concludes the laser discussion, states: “Although no real damage has yet been caused by the laser threat against airplanes, the possibility cannot be ignored that terrorist organization will use laser beams against pilots in order to carry out a terror attack. This issue becomes even more significant in light of the fact that there are particularly powerful laser devices that can be found in the possession of terrorist organizations.”
Other potential aviation threats described in the document include drones, anti-aircraft missiles, recruiting disaffected airport employees, and cyber-terrorism.
The study was published by the International Institute for Counter-Terrorism (ICT) of Herzliya, Israel, a non-profit organization that calls itself “one of the leading academic institutes for counter-terrorism in the world.”

The C-MUSIC system mounted on a Boeing 737-800
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.

It is not clear whether the filter is available at this time (May 2012). The company intends to incorporate it into glasses and night-vision goggles worn by pilots, to protect against flash blindness, meaning power densities from 100 µW/cm² up to 1000 µW/cm².

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.
