We study two-beam interaction in photorefractive sillenite crystals in reflection geometry and
derive analytic expressions for the signal gain and its polarization direction in the presence …

Exceptionally high values of photorefractive gain coefficient of up to 100 cm-1 have been
observed in Fe-doped and Fe/Tb-doped crystals of photorefractive lithium niobate. It is …

The very high birefringence of liquid crystals makes them attractive for photorefractive
applications. However, the drawbacks of using liquid crystals as photorefractives include a …

This paper presents the results of a theoretical analysis of the contribution of the inverse
flexoelectric and photoelastic effects to the photorefractive response that accompanies …

Представлены результаты теоретического анализа вклада обратного
флексоэлектрического и фотоупругого эффектов в фоторефрактивный отклик при …

The transient transmission through a photorefractive crystal in which the incident beam
couples with its own Fresnel reflection is studied. The transmission declines due to the …

The diffraction efficiency of the volume grating written and read out in Ce: KNSBN crystal by
using orthogonally polarized light beams (solid state laser with 532nm) is experimentally …

High birefringent liquid crystals are attractive for photorefractive applications but device
operation, usually restricted to the Raman–Nath regime, can be degraded by small phase …

A study of highly doped photorefractive Co: BaTiO3 reveals its usefulness for wave mixing
through reflection grating interactions. Gain and noise figures are characterized for a counter …

Strontium barium niobate SrxBa1-xNb2O6 (SBN with x= 0.61 for the congruent composition)
was synthesized and identified as a ferroelectric crystal at room temperature in the 1960s [1] …
