Frequency transformation of optical vortices upon nondegenerate multiwave interaction in dye solutions

A method for inverting the topological charge of singular light beams with their simultaneous frequency transformation under multiwave interaction in media with resonant and thermal nonlinearities is proposed. Frequency-nondegenerate four-wave and six-wave interactions of optical vortices are experi...

Description
Summary:A method for inverting the topological charge of singular light beams with their simultaneous frequency transformation under multiwave interaction in media with resonant and thermal nonlinearities is proposed. Frequency-nondegenerate four-wave and six-wave interactions of optical vortices are experimentally implemented using an ethanol solution of a polymethine dye 3274U as a nonlinear medium.
