Paper Abstract

The schemes of degenerate and nondegenerate multiwave mixing in saturable absorbers (Rhodamine 6G and polymethine 3274 U dyes) exhibiting higher-order nonlinearities have been analyzed experimentally. The role of polarization gratings resultant from spatial modulation of the light field polarization state at the orthogonal polarization of the hologram recording waves has been established. Also, it has been found that polarization of the diffracted wave is dependent on the diffraction order. The frequency conversion of coherent images from infrared to the visible and between different wavelengths of the visible region has been realized experimentally.
