Gaussian beams with optical vortex of charge 2- and 3-diffraction by a half-plane and slit

Masajada Jan

Abstract

The half-plane diffraction of the Gaussian light beam containing double and triple optical vortex is examined. The analysis is based on the scalar theory of diffraction in the Fresnel-Kirchhoff approximation. Special attention is paid to the dynamics of the optical vortex within the diffracted beam. Some results for the case of diffraction by a single slit are also presented.
