通过对离轴多程放大系统的光学设计的分析,并结合三大高功率固体激光装置的实际应用情况,指出在此类系统的光学设计中应重视抑制鬼点破坏和控制系统像差.设计的关键在于确定例行的透镜F数.并通过控制透镜的曲率半径和倾斜角度,在保证无鬼点破坏的情况下使得系统像差较小.

By analyzing the optical design in the off-axis and multi-pass amplification system,and combining the application in the three high power solid laser facilities,it is indicated that avoiding the ghost image damage and controlling the system aberration are important in the optical design of similar facilities.The key for the optical design is confirming the F number of lens,and making the system aberration least by transforming the curvature of lens and the degree of lens tilt in the case of no ghost image damager.This work could provide guidance for the optical design in similar systems.
