Abstract

The experimental and theoretical explorations of a nonparaxial Gaussian beam truncated by an aperture are discussed. A paraxial Gaussian beam passed through a short- focusing lens and forms Airy ring pattern near a waist plane. Altering of the waist beam parameter, z_o, induces the reorganization of the rings pattern. There arisen an appearance and a disappearance of the ring edge dislocation.
