Abstract. Self-conjugation of singular (vortex) beams by a static nonlinearly recorded
hologram is reported. Diagnostics of phase-conjugated vortices is implemented using an
original technique based on Young’s model of diffraction phenomena. It has been shown
that the phase-conjugated vortex is characterized by the same topological charge as the
vortex reversed through four-wave degenerate mixing being different in sign from the
vortex reflected by a common mirror.
Keywords: singular optics, optical vortices, optical phase conjugation, quadric
hologram, edge diffraction wave, Young’s interference experiment.
