The evolutions of polarization and nonlinearities in an isotropic medium induced by anisotropy of third-order nonlinear susceptibility were studied experimentally and theoretically. The anisotropy of imaginary part of third-order susceptibility was verified to exist by the change of ellipticity of polarization ellipse in the isotropic nonlinear medium CS(2). The changes of nonlinear refraction and nonlinear absorption depending upon the ellipticity of polarization ellipse are also presented. The numerical simulations based on two coupled nonlinear Schrödinger equations (NLSE) provide an excellent quantitative agreement with experimental results.
