Abstract

In this work, we present a detailed study of the on-axis intensity
distribution of the Laguerre-Gaussian beam with no azimuthal index,
diffracted by an opaque disk, by means of numerical simulation of
Fresnel-Kirchhoff diffraction integral. We investigate the effect of the
opaque disk size, the beam order, the beam waist, and the focal length.
The results show that different focal phenomena may occur including
the focal shift, focal split, and focal switch.
