| 摘 要： | 本文从高斯光束的理论出发,充分考虑到放大介质的克尔非线性效应的影响,引入了一个与之相应的非线性传输矩阵,对低重复率的钛宝石激光放大系统中的再生腔的结构性能进行了分析研究。并以此为根据,在实验上设计了激光放大再生腔,实现了TEMoo模激光振荡,并得到了腔倒空脉冲。

| Abstract: | In this article it is reported that the results of theory and experiment on the cavity of pulse-pumped Ti:Sapphire amplifier with a 10Hz repetiton rate is analysed from the theory of Gaussian beam. Specially,a nonlinear ABCD matrix is introduced to treat the propagation of beams in the amplifier crystal with nonlinearity. The numerical calculation shows that a rapid growth of the pulse energy up to 1 mJ or larger during ten to twenty round trips may lead to a mismatch between the propagation beam and the cavity modulated by nonlinear effects,and a change of beam quality. Based on the analysis,we designed a cavity for a regenerative amplifier and an intra-cavity,Q-switch,cavity dumped pulse has been obtained in our experiment |
