| Abstract: | The free-space laser communications are of potential applications in the space, the satellite lasercom terminals have reached a level of high data rate, compact and light construction, and low-power consumption in the world. This paper reviews the international progresses on the satellite lasercom, discusses the related key techniques, and gives the suggestions for the design of overall scheme. In the next paper, the test and verification techniques on the ground for satellite lasercom terminals will be introduced. |
