The advance of satellite to ground laser communication station using adaptive optics (AO) is summarized. Adaptive optics is the dominant technology to solve the atmosphere induced coherence degradation and availability reduction in the USA and Europe researching relay satellites. Key technologies, such as adaptive optics, muti-ground station receiving in day and night, and coherent communication are planned to test in these projects. It indicates that the satellite to ground laser communication is advancing to the engineering application with high date rate coherence and round-the-clock high availability. Several satellite to ground laser communication experiments have been successfully carried out in domestic, and the high availability coherent laser communication test is in progress. Adaptive optics technology has been applied in several ground stations and pretty results are obtained in the preliminary experiment. The related technology progress keeps in the same level with the foreign countries.
