Abstract

The photoelectric phenomena and orientational nonlinearity induced by nanosecond laser pulses in planar layers of liquid crystals oriented by silicon oxide (SiO) and activated with polymethine dyes were investigated. These phenomena are due to the photogeneration of surface and bulk charges in the liquid crystal cell, their spatial distribution between the grating vector and the beam propagation directions, and the electrohydrodynamic instability.
