Latest developments and trends of space laser communication

Free-space laser communication, by virtue of its bandwidth advantage, has become an indispensable and effective means for high-speed space communication in the future, and is a research hotspot in recent years. This paper gives a detailed introduction in the latest research progress and future development planning of free-space laser communication technology in the United States, Europe and Japan, and summarizes the main parameters of the free-space laser communication demonstration program at home and abroad. Through deep analysis of the latest research plan of free-space laser communication, we summarize five future development trends of free-space laser communication, namely high-speed, deep-space, multifunction, networking, and integration, as well as key technologies that are expected to break through, such as high-order modulation, high-sensitivity detection, multi-system compatibility and "one-to-many" communication. These technologies provide guidance and reference for free-laser communication equipment and related research in China.
