Paper Abstract

Light-induced 3D-structure (both stable in time and dynamic) in highly nonlinear ordered liquid with optical anisotropy are considered. The physics of discussed phenomena are determined by threshold optical non-linearity of the liquid crystals under condition of competition and energy transfer between waves with orthogonal polarizations. An intrinsic feedback for such a wave interaction, when the laser beam induces the bulk-grating of anisotropy arises because of the non-local response of the elastic medium on the external field. Dynamic scattering (diffraction) of the laser pulses (beams) on such a grating (natural or induced by external field) results in variation of their profile and makes it possible to develop the compression (squeezing) effects both in time and space.
