摘　　要：　激光预处理是使膜层提高损伤阈值的一种有效手段,现在流行的激光预处理机理模型之一是缺陷消除模型。实验从对元件膜层激光预处理前后各项参数的对比出发,分析了激光预处理对膜层的影响,说明了光学元件膜层激光预处理的过程,是对膜层去除缺陷、固化、洁净的过程。For some optical films, laser conditioning is an effective way to improve their damage threshold. The one of popular theoretical model for laser conditioning mechanism is the defects-eliminated model. In this paper, the influence of laser conditioning on optical films are analyzed by optical parameters testing of the films before and after laser conditioning. It shows that the process of laser conditioning for optical films is the films defects-eliminated, solidified and cleaned process.
