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 nonlinear Schrödinger equation and rate equation were used to study the multi-path amplification of chirped pulse in the gain medium. On this basis, the inverse problem of multi-path amplification of chirped pulse was solved by using the step Fourier and iterative method Research and simulation, that is, given the output pulse and multi-path amplification system parameters, find the corresponding input pulse waveform.The results provide a useful theoretical reference for the multi-channel amplification and shaping of the chirped pulse.
