多段阵列式放大器特性的计算模拟

考虑了从电容器储能到激光介质储能的多个能量转换环节，引入时间因子和三维空间放大自发辐射，对多段阵列式放大器９ＭＳＡ）性能作了详细的计算模拟，包括多段阵列式放大器的中间和边缘闪光阵列间的泵浦平衡、储能、增益系数和增益分布等重要激光参数随时间的变化，利用利弗莫尔实验室的实验参数对本文的程序进行了校核，并演示了该程序的预估能力。

Numerical Simulation of the Multi-Segment Amplifier

Considering the transform ation from stored energy of electric capacitors to thatof the laser m edium , and introducing the tem poral factor and three dim ensional spatial am plified spontaneous em ission ( A S E), num ericalcalculations have been perform ed to sim ulatethe characteristics of the m ulti segm ent am plifier ( M S A), including tem poral changes in thepum ping balance betw een central and side flashlam p arrays, stored energy, gain coefficientand gain distribution of the M S A. The present num erical codes have been verified w ith theexperim ental data of L L N L, dem onstrating the ability of the predicted perform ance for the M S A.
