Application Of Laser In Communication

It has various unique properties such as coherence monochromacity directionality and high intensity.

Application of laser in communication.

The technology is useful where the physical connections are impractical. In outer space the communication range of free space optical communication is currently of the order of several thousand kilometers suitable for inter satellite service it has the potential to bridge interplanetary distances of millions of kilometers using optical telescopes as beam expanders. From outer space to wall street. A beaconless acquisition via laser link means the congested lower orbits are avoided and the terminals can be lighter consume less power and offer more accuracy and security than radio.

Free space means air outer space vacuum or something similar. Laser communications systems are wireless connections through the atmosphere the light speed is the fastest speed than anything can travel so laser communications and laser sensing are important in mortar defense and other crucial aerospace and defense applications. Laser communications offer a viable alternative to rf communications for inter satellite links and other applications where high performance links are a necess slideshare uses cookies to improve functionality and performance and to provide you with relevant advertising. Laser communication systems on airport runways can send signals back to headquarters letting officers know when and what planes have landed.

Such powerful laser beams may have various applications in different fields of science research and industry. Laser light is different from an ordinary light. Current applications defense and sensitive areas. Free space optical communication fso is an optical communication technology that uses light propagating in free space to wirelessly transmit data for telecommunications or computer networking.

Take for example. Laser defense systems established across the world can detect enemy ships and missiles while at the same time disabling them. Laser is an optical device that generates intense beam of coherent monochromatic light by stimulated emission of radiation. This contrasts with using solids such as optical fiber cable.
