Abstract: | The transformation of singular light beams is analyzed theoretically for multiwave interactions on amplitude and phase dynamic
holograms in media with a resonant nonlinearity. The possibility of multiplying topological charge using different diffraction
orders is demonstrated and optimal conditions for parametric energy exchange are determined which ensure retention of the
structure of the wave front of optical vortices.
