摘要
针对环形激光谐振腔的光路变动的问题,基于SolidWorks建立了一个两平面镜和两凹面镜构成的四镜8字形稳定环形激光谐振腔模型。使用该方法分析了腔镜水平移动、垂直移动和绕光轴旋转对光路的影响,可以简单直观地观察到腔内光路的变化,并获得调节容差,模拟过程更加接近环形腔实际调节过程。当增大晶体和腔镜M1之间的距离L时,可以提高腔镜M2的水平位移容差,但角度容差有所降低,垂直容差变化不大。水平位移容差和角度容差有较强的耦合关系,腔镜水平方向的微动往往可以通过改变角度来补偿。所得到的结果对于腔设计、腔调节以及提高腔的精度具有重要的指导作用,同时可以推广到对三角形腔、正方形腔以及非平面环形腔等谐振腔的容差分析当中。
In order to analyze the change of optical axis in the ring laser resonator, the model of an 8-shaped 4-mirror ring resonator containing two flat mirrors and two concave mirrors has been established depending on SolidWorks software. It is simple and intuitive to observe the change of optical axis in the ring laser resonator with the horizontal shift, vertical shift and the rotation around the optical axis of M2, and it is more close to the actual process of the adjustment of ring resonator. When increasing the distance between M 1 and the crystal, the horizontal and angular tolerances of M2 are alterred significantly, and the vertical tolerance varys thinly. These results are important for cavity design, cavity improvement and alignment of high accuracy ring laser resonator, and it can be applied to the tolerance analysis about other resonators such as triangle ring resonator, square ring resonator and non-planar ring resonator.
