摘要：

Taking the crystal surface to be traction free, we calculate the lattice distortions and associated elasto-optic refractive-index changes induced by a photorefractive grating. The surface effects are significant and result in refractive-index changes near the surface that differ considerably from bulk values. Such surface effects should be of importance in thin-film photorefractive devices, in thin samples; and in certain situations in bulk crystals. (C) 1995 Optical Society of America
