摘　　要： 介绍喇曼感生克尔效应光谱(RIKES)的琼斯(Jones)矩阵分析方法.探测光束的传输强度不仅由所经过的每一个光学器件的琼斯矩阵所决定,而且还受到强的泵波在非线性介质样品中感生依赖于强度的二向色性和双折射(克尔效应)对琼斯矩阵的影响.同时计及样品和光学器件由强泵波作用下感生应力和其他外部产生的线双折射对喇曼感生克尔效应光谱观察的不利影响,导出测量系统的功率传输函数的完整表达式和喇曼感生克尔效应光谱的实现观察条件,最后简述以甲笨(C_7H_8)液体为试样的喇曼感生克尔效应光谱实验结果分析. The Jones matrix method analysis of Raman induced Kerr effect spectroscopy (RIKES) is presented. The intensity of weak linear polarized monochromatic probe beam is not only dependent on the Jones matrix of each optical device in pump- probe technique, but also dependent on the Jones matrix of nonlinear medium sample, in which an intensity dependent dichromism and birefringence are induced by a strong circularly polarized pump beam. Take account of the disadvantage factors of the additional static birefringence in the sample and other optics, which will produce a background intensity in the polarized signal. The complete expression of power transfer function and the annihilation condition of RIKES are derived. The RIKES experimental results of the toluene (C7H8) are given briefly.
