带有共焦光学延迟系统的长腔CPM染料激光器的稳定性研究

Study on stable zone of a long ring cavity for CPM dye laser with optical delay system

本文对带有共焦光学延迟系统的8镜环形激光器的稳定域及腔内光束参数进行了系统的计算和分析,得到不同腔长时的最佳大曲率半径、腔长一定时的稳定域宽度以及腔内光束参数随大曲率半径的变化规律。

The siable zone and waist size of an eight mirror long ring cavity with optical delay system in a colliding pulse mode-locked (CPM) dye laser is first calculated and analysed. The optimal largo radius of curvature for various cavity length and the dependence of the stable zone of cavity and the beam waist size on the large radius of curvature for a fixed cavity length are obtained.
