| 摘 要： | 高功率激光系统中鬼光束对元件安全造成威胁,并导致主光束质量变坏,故鬼光束会聚点的位置和鬼光束会聚光斑光强的定量分析,对高功率激光系统安全运行非常重要。提出了用“镜像法”分析高功率激光系统中非共轴光路鬼点的方法。即将光路在各反射镜处“镜像”,由“镜像”得到等效光学系统,对等效系统进行鬼点分析后,再将鬼点“镜像”回原非共轴光学系统。结果表明,非共轴光学系统的鬼点情况,可由其“镜像”等效系统决定。

| Abstract: | In high power laser systems,ghost light can be so strong to damage optical elements,air may be ionized,resulting in the quality of light going bad.There fore,it is rather important to locate the ghost images and to calculate the intensity of ghost images quantitatively.The method of mirror imaging is introduced to deal with the multi-axial optical system,that is,all elements are imaged to axis of one element,after analysize the ghost image of the equivalent optical system,then the ghost images are imaged to the original multi-axial optical system. |

| Keywords: | high power laser system ghost image matrix optics multi-axial light path |
