摘　　要：建立了用于研究光脉冲在钕玻璃激光放大介质中传播特性的模拟软件。它综合考虑了激光放大介质中基质的克尔非线性效应、群速度色散、活性粒子的增益谱以及增益饱和对光脉冲传播特性的影响。所得结果对高功率钕玻璃激光放大器的设计和优化有参考价值。The software aiming at simulating the propagation of optical pulse in Nd: glass laser amplifying medium has been completed. The effects of the Kerr nonlinear effect, group velocity dispersion, and gain spectrum and gain saturation of active particles in the laser amplifying medium on pulse characteristics have been taken into consideration simultaneously. The results obtained from the simulation are helpful to the design and optimization of Nd: glass laser amplifier systems with high power.
