通过对国内首次采用离轴式构型的高功率固体激光器双程放大实验中自激振荡的实验 ,分析了自激振荡产生的原因 ,在不需增加隔离器的情况下得到了抑制自激振荡的方法 ,从而为解决多程放大实验中的自激振荡问题提供了具体的指导方法。
Through the experiment of the self-excited oscillation in the experiment of two-way amplification of the high-power solid-state laser with the off-axis configuration for the first time in China, the cause of self-oscillation is analyzed. The self-oscillation is suppressed without increasing the isolator Method, so as to solve the multi-path amplification experiment self-oscillation problem provides a specific guidance.
