摘要: 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。Abstract: A 1 D computer codes which adopted the equivalent lifetime of the terminal level relaxation to describe the gain recovery was developed for multipass amplification system. The simulation results of the 4 pass amplifier system with a small aperture reverser showed 1ns square pulse(1ω) with 2.8kJ energy could be obtained by employing 14 Nd:glass disks. The detail schemes and their characteristics of the system were given in the paper.
