摘　　要：在惯性约束聚变(ICF)高功率激光装置中,自适应光学波前控制技术是确保装置安全顺畅通光以及光束质量达标的关键技术之一。本文介绍了我国ICF激光装置中波前控制技术从概念的提出到大规模应用的研究和发展历程,重点介绍了在装置不同发展阶段针对装置的需求所研究和发展的关键系统技术,包括基于远场焦斑优化的爬山法波前控制技术、基于双波前传感器数据融合的全装置波前控制技术,以及旋转腔激光装置结构中基于双变形镜的全系统波前控制技术,并介绍了相关技术在装置上的应用结果。In the high-power laser system for inertial confinement fusion,wavefront control is one of the key technologies for the laser system to ensure it operates safely and reaches the beam quality criteria.In this article,the development of the wavefront control technology from its first being putting forward for the ICF laser system to its application in the latest ICF laser system in China was introduced.During the development of the ICF facilities,the wavefront control methods are varying to satisfy the varied demands promoted by these facilities.Based on different facilities,the methods and the application results are illustrated,including the climbing wavefront method for far-field spot optimization,the full-facility wavefront control method based on the data fusion acquired from two wavefront sensors,and the full-system wavefront control method with bi-deformed mirrors in the rotation chamber laser structure.
