    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 a... Show More

    Abstract: The ellipsometrical analysis of the external specular reflection of light on nonabsorbing superficial films allows us to know factors which influence the ellipsometric measurement of the analyzed system. For optical nonabsorbing superficial films the curves =f(df) and =f(df) are periodical, while the curves =f() are closed. The paper presents o... Show More
