Paper Abstract

The investigation of the first order Bessel beam diffraction on a binary amplitude diffraction mask with two open zones has been performed. It has been shown by computer modeling and experimentally that the structure of the beam intensity distribution along the propagation axis resembles a chain-like beams structure, but a dark hole can be observed along the propagation axis in the center of the beam. The interference pattern of the beam under investigation and Gauss beam has demonstrated the phase singularity presence. The transverse intensity distribution of the beam has shown ring structure with periodically changing intensity.
