摘　　要：利用非线性薛定谔方程 ,详细研究了放大介质的增益窄化和增益饱和效应对超短脉冲在放大介质传输特性的影响 ,以及传输过程中B积分的影响 在此基础上 ,对超短脉冲放大系统的逆问题进行了研究 ,即在给定放大系统参数和满足物理实验要求的输出脉冲波形前提下 。The effects of the gain narrowing, gain saturation, as well as B integral on the ultrashort pulse propagating through the amplified medium were studied by using the nonlinear Schrdinger equation. The inverse problem of the ultrashort pulse propagating through amplifier was studied, i.e., the corresponding input pulse could be calculated from the given parameters of the amplifier and the requirement of the physical experiment. The results were useful for the design of the pulse shaping of the ultrashort pulse amplifier.
