提出并分析了一种测量气体电子克尔参数和转动参数的方法。它是基于分析的光谱特性的光脉冲传播后，通过空芯光纤，其中填充有气体的特征参数被测量。通过数值实验对该方法进行了进一步的研究，反演的数据与模拟传播动力学的模型中使用的系数吻合得很好。该方法可用于研究各种材料在气相中的非线性极化率。
A method for measuring electronic Kerr and rotational parameters of gases is proposed and analyzed. It is based on analyzing spectral characteristics of the optical pulse after propagation through a hollow-core fiber which is filled with the gas whose characteristic parameters are to be measured. The method is further investigated through numerical experiments, and the retrieved data agree well with the coefficients used in the model simulating the propagation dynamics. This method can be used to study the nonlinear polarizability of various materials in gas phase.
