Abstract

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.
