Abstract
Using variational method for an elliptical Gaussian optical beam trial function, self –action in bulk chalcogenide glass (Kerr media) is investigated. Emphasis is laid on the study of variation in beam width, curvature, phase and intensity of the beam with propagation distance. Solutions predict stationary self-focusing of the elliptical beam and an effective beam collapse at 10Pcr input power. These study is significant in the choice of parameters in optical communications
