摘　　要：自适应光学(AO)作为一种主动光学补偿技术,由于具有结构简单、校正效果好、可闭环运行等优势,被大量用于校正激光波前畸变,并于近年逐渐应用于高能激光器系统中。综述了AO系统工作的基本原理,系统论述了近年来国内外在AO系统校正固体激光畸变方面的研究进展。按照校正固体激光器波前畸变的AO系统中有无采用波前传感器,将其分为无波前探测和有波前探测的AO校正技术进行介绍,分析了各个研究工作的关键性技术。最后总结了目前存在的技术难题,并对AO技术在固体激光器中的应用前景进行了展望。As an active optical compensation technology, adaptive optics （AO） is used to correct wavefront distortion extensively because of its advantages such as simplicity, instantaneity and validity. In recent years, AO technology is increasingly used in high- energy laser system. We review the basic principles of the AO system, and discuss the research progress of solid-state AO correction technology at home and aboard. Introduction to two categories is presented according to if there is a wavefront sensor in an A0 system to correct the wavefront distortion in solid state lasers, and the key technologies are introduced. Finally, theexisting technical difficulties are summarized, and the application prospect is presented.
