摘　　要：利用非线性薛定谔方程和速率方程,研究了啁啾脉冲在增益介质中多程放大的特性.在此基础上,利用分步傅里叶和迭代法对啁啾脉冲多程放大的逆问题做了研究和模拟,即在给定输出脉冲和多程放大系统参数的情况下,求出相应的输入脉冲波形.有关结果对啁啾脉冲的多程放大及整形提供有用的理论参考.The multipass amplification characters of the chirped pulse in gain medium were studied with the Schroedinger equation and population equation. The inverse problem of multipass amplification of the chirped pulse was studied and simulated by means of the Split-step Fourier and iteration methods, to find the profile of the input pulse from the given output pulse and multipass amplification parameters. The results are useful for the multipass amplification and design of the pulse shaping of the chirped pulse
