为了有效地避免鬼像破坏,针对采用离轴多程放大的高功率固体激光实验装置的光路特点,利用“光路二叉树”原理和“矩阵光学”方法,将全光路“单元化”为主放大、助推放大、反转器和输出4个部分进行光线追迹和鬼像分析,给出了各个部分的主要鬼像分布·并通过将鬼像分析的结果与前期实验中发现的现象进行比对,证明了此种分析方法的可行性和可靠性·从而为在今后实验装置的改造和类似系统的设计中有效的分析和规避鬼像提供了理论和实验依据· In order to effectively avoid the ghosting damage, aiming at the optical characteristics of a high power solid-state laser experimental device with off-axis multi-path amplification, the “optical binary tree” principle and the “matrix optical” Boosting the amplifier, inverter and output of four parts of the ray tracing and ghosting analysis, given the various parts of the main ghost distribution, and by comparing the results of the ghost image analysis with the previous experiment found , Demonstrating the feasibility and reliability of this method of analysis and thus providing both theoretical and experimental evidence for the effective analysis and avoidance of ghosting in the future retrofitting of experimental devices and the design of similar systems
