Paper Abstract

The light-induced hydrodynamic instabilities in initially homogeneously oriented nematic liquid crystals (NLC) are detected and studied for the first time at the excitation of convective flows and orientational dynamic structures with complex (periodic) topology, producing the self-induced diffraction and scattering of the light accompanied with optical bistability. These phenomena are caused solely by intrinsic multiplicative feedback arising in a spatially distributed system (highly nonlinear absorbing NLC) for an all-optical experiment without any external quasi-stationary field and initial temperature gradient.
