Overview of space laser communications

This paper describes the basic process of laser communications and their link types firstly. Then, it focuses on the latest developments of the laser communications in the European Space Agency（ESA） , the U- nited States, Germany, Japan, and domestic laser communication research, and also gives detailed technical parameters of some successful applications for the laser communication terminals in space, such as laser wave- lengths, communication distances, communication speeds, bit error rates, and application purposes. It high- lights the characteristics and advantages of each instrument in opto-mechanical structure, points out the key technical problems faced by the laser communications, as well as the future development of laser communica-tion trends and directions through the analysis of the research status at home and abroad, which will provide a reference for the study of laser communication equipment and its related fields.
