This is the authors' abstract. We don't add key points for this paper.
An analysis of a frequency transformation of singular light beams by the dynamic hologram at a frequency nondegenerated four-wave mixing in dye solutions has been carried out. The transformation of optical vortices of the first and second order from the infrared spectrum to the visible one has been demonstrated experimentally with simultaneous inversion of the topological charge.
