Abstract
Summary form only given. The self-action of a light beam of the Gaussian profile with a distribution of elliptical polarization uniform in the cross-section in a nonabsorbing medium with spatial dispersion of cubic nonlinearity has been investigated numerically. We have analyzed the dependences of the intensity, the degree of ellipticity and the rotation angle of the main axis of a beam polarization ellipse on the transverse coordinates and length of the medium. It has been established that nonlocality of a nonlinear optical response of the isotropic medium and elliptical polarization of incident radiation strongly affect the threshold conditions of self-focusing and substantially change the character of propagation of Gaussian beams.
