Annotation: We analyzed the influence of inverse piezoelectric effect on the maximal value of diffraction efficiency of the reflection hologram recorded in cubic photorefractive Bi₁₂TiO₂₀ crystal. It is shown that the influence of the inverse piezoelectric effect can vary a value of an optimal azimuth of the reference wave for which maximal value of the diffraction efficiency of the reflection hologram can be achieved.

Keywords: reflection hologram, photorefractive crystal, diffraction efficiency, azimuth of polarization
