Abstract

Summary form only given. Recent advances in the nonlinear optics of liquid crystals (LC) are related to optically induced collective molecular reorientation processes. These processes exhibit features such as propagation-induced reorientation and self-oscillations. Jumps and hystereses of an LCs orientational state with changing incidence angle and intensity of light provide new schemes for optical bistability and optical modulation. In certain circumstances, direct orientational interaction may be suppressed by absorption-induced effects. Among several mechanisms for the transformation of the energy of an absorbed light beam into molecular reorientation, the strongest one utilizes generation of hydrodynamic motions. In this way, e.g., infrared-visible modulation is possible at a microwatt power level.
