Abstract

The general equations applicable to the description of different photorefractive effects in electro-optic crystals, taking into account their piezoelectric properties, have been considered in this paper. The photorefractive gratings formed by plane light waves slowly changing in time in boundless piezoelectric media have been analyzed in detail. The influence of piezoelectric properties of the crytals on the effective static dielectric constant at different orientations of the photorefractive grating vector has also been considered.
