摘要
当入射激光强度较高时(～10^(13)W/cm^2),非线性介质的五阶非线性效应巳不能忽略.前文仅考虑三阶非线性效应的影响,得到输出脉冲的非对称展宽,计算结果与实验结果基本符合.本文在前文的基础上,同时考虑三阶和五阶非线性x^(3)和x^(5)的影响,得到更好的结果.
The fifth-order nonlinear effects of medium must be included when the incident laser intensity is higher ( -1013 W/cm2). By using plane-wave theory and considering both the third-nonlinearity and the fifth-order nonlinearity, the asymmetric Stokes-anti-Stokes broadening of output pulse is obtained through solving Maxwell equation directly. The theoretical result agrees well with the experimental data reported by Fork. et. al..
