Abstract

Considerable recent attention has been focused on the investigation of `nondiffracting beams.' This term was introduced for the denotation of the zero order Bessel beam propagating in the homogeneous medium. Similar to the unlimited plane wave, the `nondiffracting beam' does not spread during propagation, but has the maximum of intensity at the optical axis. This article discusses possibilities for forming `nondiffracting beams' with the help of diffractive optical elements. The results of the modulated axicon experimental investigations are represented.
