| 摘 要： | 在考虑了激光放大介质中基质的克尔非线性效应和群速度色散以及活性粒子的增益分布后，导出了光脉冲在激光放大介质中传播的基本方程。并在光脉冲中心频率与介质增益峰值频率时重合时，对皮秒超高斯光脉冲在钕玻璃激光放大介质中传播的脉冲形状进行了分析讨论。

| Abstract: | After considering Kerr nonlinear effect, group velocity dispersion of host and gain distribution of active particle in laser amplifying medium, a basic equation describing the propagation of an optical pulse in laser amplifying medium has been deduced. Besides, the profile and power spectrum of a ps super Gaussion pulse along Nd３＋：glass laser amplifying medium length have been disscussed when its central frequency coincides with peak frequency of gain of laser amplifying medium. |
