AbstractBased on the background of data relay satellite (GEO) to ground laser communication system, we analyze influence of slant atmosphere channel on the coupling efficiency of space light to multimode fiber, and we present a solution with adaptive optics technology to overcome the difficulty of low coupling efficiency when collecting with large aperture in receiver terminal. The feasibility analysis of satellite to ground laser communication based on adaptive optics technology is made. In order to verify the effectiveness of the proposed scheme, laboratory experiments of 2.5Gbps laser communication based AO are carried out. The results shows: average received power increases 4.52dB, severe signal fading is controlled effectively, average bit error rate (BER) reduces and the scheme of satellite to ground laser communication with adaptive optics is correct. © 2012 SPIE.; Based on the background of data relay satellite (GEO) to ground laser communication system, we analyze influence of slant atmosphere channel on the coupling efficiency of space light to multimode fiber, and we present a solution with adaptive optics technology to overcome the difficulty of low coupling efficiency when collecting with large aperture in receiver terminal.
