摘　　要：在综合考虑了激光放大介质的克尔非线性效应、群速度色散和净增益后,得出了光脉冲在放大介质中传播的基本方程。以钕玻璃放大介质为例,对短脉冲在放大介质中的传播特性进行了数值模拟,并重点讨论了啁啾脉冲频率波动对其传播特性的影响。After considering simultaneously Kerr nonlinear effect, group velocity dispersion and net gain in laser amplifying medium, a basic equation describing the propagation of an optical pulse in amplifying medium has been deduced. As an example, the propagation characteristics of a short pulse in Nd： glass laser amplifying medium has been simulated numerically, and the effect of chirped pulse frequency fluctuation on its propagation characteristics has been discussed emphatically.

关 键 词：激光放大介质 啁啾脉冲 频率波动 净增益
