红光Nd:YAG激光器用光学薄膜的研制

Development of Optical Thin Films for Red Nd:YAG Laser

从产生660nm红光Nd:YAG激光器制作机理出发,分析了其使用的几种光学薄膜,采用光学薄膜理论的矢量合成方法,利用计算机膜系设计软件优化,并经过适当修正后得到便于控制的短波通膜系、二倍频高反射膜系,选择适当的薄膜材料和工艺参数,制备出与理论计算结果相吻合的几种光学薄膜,满足技术指标要求。

Based on the manufacturing theory of 660nm red Nd：YAG laser, A series of optical thin film for the laser system were analyzed, using vetorial resultant method ofoptical thin-film theoretical design, utilizing computer coating optimization methods based on the starting design, after appropriate amendment, we have obtained the controllable film system of short-wavelength pass and doubling frequency high reflectance, selected appropriate thin-film material and technological parameter, the results show that there is good compatibility, deposited films can meet the practical requirement.
