Transformation of Topological Structure of Optical Vortices upon Frequency Non-Degenerate Four-Wave Mixing.
D. V. Gorbach, A. L. Tolstik, and O. G. Romanov

The method for topological structure transformation of optical vortices with simultaneous frequency conversion in a medium with resonant and thermal nonlinearities was theoretically introduced on the basis of holographic principles for optical image processing. Frequency non-degenerate four-wave mixing of singular light beams was realized experimentally when recording and reading of nonlinear dynamic holograms in organic dye solutions.
Key words: optical vortice, nonlinear dynamics, hologram
