近对称谐振腔的变换圆图解分析
Transform-circle graphic analysis of self-mode-locked laser cavity
-
摘要: 利用传播圆-变换圆图解分析方法,通过对不同结构谐振腔的分析和对比,得出一种宜于推广的自锁模激光谐振腔——近对称谐振腔,其锁模运转易于启动且工作性能比较稳定;通过实验对近对称腔的工作性能进行了验证,并对一种五镜锁模腔进行了分析。五镜腔实质上等价于近对称四镜腔。Abstract: Using the propagation-circle and transform-circle graphic analysis, cavities with different configurations were analyzed and compared and a self-mode-locked cavity, a nearly symmetrical four-mirror cavity was obtained, which was more stable and easy to start. The operating performance of the nearly symmetrical cavity was ensured by experiment. A five-mirror mode-locked cavity was also analyzed.
