Abstract

A number of cubic photorefractive crystals (CPC) have piezoelectric properties and natural gyrotropy simultaneously. It is known ¹⁻³ that while recording holographic gratings (HG) in photorefractive piezocrystals there has been existed the secondary contribution to the disturbances of optical properties of the medium. It depends on joint action of piezoelectric and photoelastic effects. The secondary contribution can be taken into account by introducing effective electrooptic constants r'_mnp ¹⁻³. The account of gyrotropic properties of CPC in terms of approximation of coupled waves for arbitrary orientation of the grating vector k in the plane (110) has been carried out in the paper⁴.
