Laser beams are used in modern communication systems to send signal over long distances through optical fibres they are also used to perform bloodless surgery. In particular, free space laser communication has useful applications to military logistics, where information on the front must be kept limited to friendly ears, and ground-to-air links are important. Solar blind ultraviolet communication techniques have promise to address the military's needs for short range applications where non-line-of-sight and a low probability of interception and detection is required. In laser torch based communication system project we implemented a new generation laser torch-based voice transmitter and receiver which is a good replacement for the present day communication systems. Laser defense systems established across the world can detect enemy ships and missiles while at the same time disabling them airport runways laser communication systems on airport runways can send signals back to headquarters letting officers know when and what planes have landed.
