Zusammenfassung: | To generate hollow chain-like beams the diffraction of the first order Bessel
beam by zone plate with two odd open Fresnel zone has been investigated. It has
been shown that the capsules size is influenced by the number of the second odd
open Fresnel zone and by the zone plate focal length. A hollow chain-like beam
has been experimentally generated as a result of the first order Bessel beam
diffraction by zone plate with the first and the ninth open Fresnel zones. The
orbital angular momentum presence has been proved experimentally. The main
features of the beam have been investigated. Sufficiently good agreement
between experimental and numerically calculated results has been demonstrated. |
