Laser dazzler

A dazzler is a non-lethal weapon which uses intense directed radiation to temporarily disable its target with flash blindness. Targets can include sensors or human vision.

Initially developed for military use, non-military products are becoming available for use in law enforcement and security.

Dazzlers emit infrared or invisible light against various electronic sensors, and visible light against humans, when they are intended to cause no long-term damage to eyes. The emitters are usually lasers, making what is termed a laser dazzler. Most of the contemporary systems are man-portable, and operate in either the red (a laser diode) or green (a diode-pumped solid-state laser, DPSS) areas of the electromagnetic spectrum. The green laser is chosen for its unique ability to react with the human eye. The green laser is less harmful to human eyes.

Some searchlights are bright enough to cause permanent or temporary blindness, and they were used to dazzle the crews of bombers during World War II. Whirling Spray was a system of search lights fitted with rotating mirrors which was used to dazzle and confuse pilots attacking the Suez canal. This was developed into the Canal Defence Light, a small mobile tank mounted system intended for use in the Rhine crossings. However, the system was mainly used as conventional searchlights.

Handgun or rifle-mounted lights may also be used to temporarily blind an opponent and are sometimes marketed for that purpose. In both cases the primary purpose is to illuminate the target and their use to disorient is secondary.

The first reported use of laser dazzlers in combat was possibly by the British, during the Falklands War of 1982, when they were reputedly fitted to various Royal Navy warships to hinder low-level Argentinian air attacks.
