摘要
重点研究了高功率固体激光装置自适应光学系统的两个主要应用问题,包括波前传感器参考波前在线标定和预补偿方式下激光过滤波器小孔堵孔问题。文中对两种不同的在线标定方法进行了研究,分析各自的优缺点,结合自适应光学系统的校正对象确定合适的标定方法和标定结果。针对小口径注入位置预补偿的自适应光学布局方案,对影响过滤波小孔的主要因素进行了研究,并从自适应光学系统控制和激光器运行流程两个方面提出了解决方案,获得较好的实验结果。
Abstract
Online calibration of wave-front sensor's reference plate and problem of pre-corrected laser being clipped at pinhole are two key factors when adaptive optics system is used in high power solid-state facility. The advantages and disadvantages of the two calibration methods have been researched, and calibration methods and results are chosen by considering adaptive optics system controlling object. For the pre-compensation program, the main factors of laser clipping problem have been researched, and the problem can be solved by adaptive optics system control model and laser system operation process. Satisfying experimental result is achieved.
