摘　　要：对透明和吸收介质的简并四波混频理论作了处理,实验上给出了掺半导体玻璃,无机和有机材料的三阶非线性极化率x^(3)和非线性折射率n_2的值,而且确定了非线性参数x^(3)的时间响应特性,实验装置的时间分辨率为5ps.This paper deals with the theory of degenerate four- wave mixing (DFWM) in trantarent and absorbing media. The values of third order nonlinear susceptibilities x(3) and nonlinear refractive index n2 in semiconductor doped glass, inorganic and organic media were given experimentally. The time response properties of the nonlinear susceptibility X(3) was also determined. Time resolution of the experimental device is 5 ps.
