采用下级能等效寿命来描述多程放大系统的增益恢复问题，并在此基础上建立了较为准确的多程放大系统能流分布的１维模拟程序。对带小口径电光开关的四程放大系统构型各种基本排布的模拟表明，采用１４张钕玻璃片即能达到单路输出２．８ｋＪ（１ω，１．５ｎｓ）的要求。给出了满足要求的排布方案并分析比较了工作特性
The equivalent lifetime of the lower stage is used to describe the gain recovery problem of multi-path amplification system. On the basis of this, a more accurate 1-D simulation program of multi-path amplification system energy flow distribution is established. The simulations of various basic arrangements for a four-way amplifier system with a small-diameter electro-optical switch show that using 14 neodymium glass sheets can achieve a single output of 2.8 kJ (1ω, 1.5 ns). The arrangement scheme to meet the requirements is given and the working characteristics are analyzed and compared
