激光棒位置对热不灵敏腔运行特性的影响
Influence of laser rod position on the thermal insensitive resonators
摘要
对于给定的腔型,为获得最大的稳定激光输出,必须选择最佳的激光棒位置.运用激光谐振腔的矩阵理论,给出了内含热透镜的三种腔型下的g参数以及棒位置对运行特性的影响,使用Matlab软件分别进行了理论模拟,在泵浦电压1000 V、重频10 Hz、晶体对称置于腔中间的条件下,通过实验验证了部分理论结论,对谐振腔的设计具有一定的指导作用.
Abstract
For a certain resonator,it is necessary to find out the optimum position of the laser rod to achieve maximum output power.By using the matrix theory,effect of g-parameters for different laser cavity and different laser rod position on the operation of a thermal insensitive solid state laser resonator is presented.In the condition as 1000 V bump votage at 10 Hz repetition frequency with the crystal in the middle of the resonator,the experimental results seem quite similar with theoretical prediction by using matlab software.The conclusions are of benefit to the design of resonator.
