Abstract
Investigations of interaction of laser beams with liquid crystals reveal new fundamental features of nonlinear dynamic systems. Those features are connected with the giant values of optical nonlinearity, multitude of control parameters, specific properties of light propagation in highly anisotropic and inhomogeneous media, and multidimensional (vector) character of light-induced modulations of liquid crystals. Exceptional opportunities to visualize complex spatio-temporal phenomena in real time, in simple experimental situations, and with utilization of low-power lasers and thin layers of materials, provide a great potential for the design of low-cost and portable set-ups for modeling, demonstrations, and general educational purposes.
