| Popis: | Phase conjugation of singular (vortex) beams is performed using a static nonlinearly recorded hologram. The diagnostics of phase-conjugate optical vortices is carried out by an original method based on the Young model of diffraction phenomena. It is shown that a phase-conjugate vortex is characterized by the same topological charge as a vortex inverted by degenerate four wave mixing, differing in sign from a vortex reflected by an ordinary mirror. |
