摘　　要：采用增益预抽运技术改善被动调Q固体激光器输出的不稳定性,并在Cr^(4+),Nd^(3+):YAG双掺自调Q晶体上得到实验验证。与连续抽运和脉冲抽运条件下的激光脉冲参数进行比较,激光脉冲的频率稳定性和幅值稳定性都有大幅度提高,并在实验基础上给出了预抽运参数的优化结论。Using pre-pumping mechanism to improve the stability of passively Q-switched lasers, it has been verified with Nd3+, Cr4+:YAG. Compared with CW pump and pulse pump, the stability of both frequency and amplitude for pre-pump is much improved. Finally, the experiment results of optimization of pre-pumping parameters are given.
