A comparison of the thickness dependences of the diffraction efficiency of the reflection holographic gratings in cubic photorefractive crystals of (110) and (111) crystallographic cuts is fulfilled. The theoretical model is based on the standard coupled wave theory with taking the linear electro-optic, inverse piezoelectric, photoelastic effects and optical activity of the crystals into account. The possible influence of the inverse flexoelectric effect on diffraction efficiency of the reflection hologram formed in the photorefractive crystals is considered too. Properties of the inverse flexoelectric effect tensor for photorefractive crystals of 23 and classes and expressions for the coupling constants for wave equations are analyzed.
