利用ABCD传输矩阵对多片串接正支非稳腔进行分析,给出了谐振腔最优参数,并利用谐振腔自再现条件计算不同薄片上的振荡光束尺寸,根据理想谐振腔阈值条件,得到谐振腔的输出能量。针对上述分析进行了实验验证,在非稳腔放大率为2.0、重复频率为25Hz、脉宽为250μs的条件下,输出单脉冲能量为10.52J,斜效率为22.75%,实验结果与理论设计基本吻合。
The ABCD transfer matrix is used to analyze the stability of the multi-piece positive connected steady unbalance cavity, and the optimal parameters of the resonator are given. The size of the oscillating beam on different slices is calculated by the self-reproducing condition of the resonator. According to the ideal resonant cavity threshold condition, The resonant cavity output energy. Experimental results show that the single-pulse output energy is 10.52J and the ramp efficiency is 22.75% under the conditions of unsteady cavity magnification of 2.0, repetition frequency of 25Hz and pulse width of 250μs. The experimental results are basically consistent with the theoretical design Anastomosis.
