高功率激光通过多级和多程脉冲放大器的传输特性

Propagation properties of high power laser beams passing through multistage and multipass pulsed laser amplifiers

采用脉冲序列模型和薄片模型，对任意空间和时间分布波形的激光通过任意增益分布多级和多程脉冲放大系统的传输特性作了详细研究。

By using the pulse sequence model and the slab model that the active medium is divided into a series of thin slabs with certain gain distribution and loss factor,the propagation properties of laser beams with arbitrary spatial and temporal profiles passing through multistage and multipass pulsed laser amplifiers with arbitrary gain distribution have been studied in detail.
