Light wave diffraction on reflection holograms in a cubic piezoelectric crystal

Hologram recording and reading in cubic gyrotropic photorefractive piezocrystals (review)

“…Especially interesting effects were observed during a study of the output energy characteristics of phased reflected holograms in cubic optically active photorefractive piezocrystals as a function of crystal thickness [130,133,[135][136][137][138]. The study of these effects showed that the (001) cut is optimal for reflected holograms only up to a certain crystal thickness.…”

“…Reflected holograms in optically active cubic crystals were examined in many studies [113,[126][127][128] in terms of only the electro-optical mechanism of the photorefractive effect although they were already investigated taking into account the piezoelectric effect [70,[129][130][131][132][133][134][135][136][137][138]. Especially interesting effects were observed during a study of the output energy characteristics of phased reflected holograms in cubic optically active photorefractive piezocrystals as a function of crystal thickness [130,133,[135][136][137][138].…”

Dynamic Denisyuk holograms in cubic photorefractive crystals

“…However, this statement is not valid for cubic photorefractive optically active crystals. Studies performed in [32] showed that for certain crystal thicknesses, the (111) cut is preferable than the (001) cut both to obtain a high signal gain and to optimise the diffraction eféciency. Note that the polarisation dependences of the two-beam ampliécation eféciency of the phase-modulated signal wave on the reêection photorefractive grating in three identical (111) BSO, BTO and BGO crystals were studied in detail in paper [33].…”

“…Of great practical interest is the problem of determining the maximum achievable polarisation-optimised output parameters of the reêection holograms written in cubic optically active crystals in the Denisyuk scheme and the study of the dependence of these parameters on the crystal thickness and cut. This problem was partially considered in [32] and more completely solved in papers [34 ë 36] by using the indicating surface method. The indicating surfaces of the polarisation-optimised diffraction eféciency of reêection holograms in a cubic photorefractive optically active crystal were constructed and analysed in [35].…”
