Abstract
Taking the crystal surface to be traction free, we calculate the latti ce distortions and associated elasto-optic refractive-index changes in duced by a photorefractive grating. The surface effects are significan t and result in refractive-index changes near the surface that differ considerably from bulk values. Such surface effects should be of impor tance in thin-film photorefractive devices, in thin samples; and in ce rtain situations in bulk crystals. (C) 1995 Optical Society of America
