摘　　要：给出了具有几个光振荡周期长的飞秒激光脉冲在不考虑群速色散的情况下传输方程的解。用数值方法模拟了飞秒激光脉冲的非线性传输 ,考察了非线性效应对脉冲形状和频谱的影响 ,得到和慢变振幅近似下不完全一致的结论。The solution of propagation equation of femtosecond laser pulse with duration of several optical oscillation periods is presented without consideration of group velocity dispersion.By simulating numerically the nonlinear propagation of femtosecond laser pulse,we investigated the influence of nonlinear effect on pulse shape and spectrum.The result we got does not coincide exactly with that of slowly varying envelope approximation.
