由激光速率方程和泵浦速率的空间和时间分布出发，采用了二维光线追迹和蒙特卡罗法模拟了放大自发辐射，研究了多段阵列式钕玻璃放大器（ＭＳＡ）中间板条增益分布随时间和泵浦速率的变化。所得结果对大尺寸多段阵列式钕玻璃放大器的设计有参考价值
Based on the spatial and temporal distribution of the laser velocity equation and the pump velocity, two-dimensional ray tracing and Monte Carlo method were used to simulate the amplification of spontaneous emission. The gain distribution of the middle slab of multi-segment array neodymium glass amplifier (MSA) Time and pump rate changes. The results obtained for the design of large-size multi-segment array neodymium glass amplifiers have reference value
