摘　　要：本文介绍了为"神光-Ⅲ"主机装置研制的五十套工程化自适应光学系统,包括系统技术方案,基于可拆卸技术的大口径变形镜和具有自动对准功能的哈特曼波前传感器两主要部件的性能,测量并分析了波前特性,系统校正结果表明:自适应光学系统改善了主机装置的光束质量,满足10倍衍射极限范围内激光能量大于95%的指标要求,确保"神光-Ⅲ"主机装置激光在主放大系统内的传输顺畅。The fifty engineered-manufacture adaptive optics systems developed for the Shen Guang Ⅲ（SGⅢ） facility, are introduced in this paper. The system technical scheme, together with the key components – the dismountable large aperture deformed mirror and the auto-alignment Shack-Hartmann wavefront sensor, are presented. The characteristic of the wavefront is measured and analyzed. The result of system correction shows that the adaptive optics systems improved the beam quantity of the SGⅢ facility, meet the requirement that the laser beam energy is higher than 95% in the 10-time diffraction limit zone, and ensured the laser transmission in the main amplification system of the SGⅢ facility.
