Direct photodetection space laser communications
Abstract
Studies and experiments related to the development of an optical communications system in space are reviewed. Such a system consists of two distinct subsystems. The transmitter subsystem contains a transmitter laser and a beacon receiver. The receiver subsystem is composed of the receiving optics with the detector, a local oscillator laser for heterodyne detection applications, and a beacon transmitter. Direct detection systems are discussed, giving particular attention to a current laser space communication program which uses Nd:YAG lasers
