A laser warning receiver is a type of
warning system used as a passive military defence. It detects, analyzes, and locates directions of
laser
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word "laser" is an acronym for "light amplification by stimulated emission of radiation". The ...

laser dazzler
A dazzler is a non-lethal weapon which uses intense directed radiation to temporarily disorient its target with flash blindness. They can effectively deter further advances, regardless of language or cultural barriers, but can also be used for h ...

Detectors used in LWR are usually based on a semiconductor photodetector array, which is typically cryogenically or thermal-electric cooled. Sometimes avalanche photodiodes (APD), photoconductivity, photoelectromagnetic, or photodiffusion devices are used even without cooling. Some devices detect only the main beam of foreign lasers while others detect even scattered rays.
