Light wave diffraction on reflection holograms in a cubic piezoelectric crystal

AbstractAnalytical expressions for the electric field strength in a signal wave formed during the interaction of opposite waves in a cubic photorefractive piezoelectric crystal are obtained in the given grating approximation. As a result of the optical activity of the medium, the amplification coefficient and the diffraction efficiency of a hologram in the

The results of investigations into the dynamics of the light-induced absorption and of its dark relaxation in a Bi12TiO20 : Ca single crystal are presented. To illuminate the crystal and to measure the induced changes in the absorption, narrow-band radiation of an incoherent semiconductor light-emitting diode with the wavelength λ = 660 nm close to that of a helium-neon laser was used. The material parameters of the crystal are estimated based on a comparison of the experimental data with the results of calculations for a theoretical model that takes into consideration doubly ionized donor centers and shallow traps.
