For sinusoidal phase modulation of a signal beam with frequency Ω ≫ 1∕τ, where τ is the characteristic time of photoinduced charge redistribution over donor and trapping centers, the photorefractive reflective hologram formed in a crystal by a diffusion mechanism can be regarded as steady-state.…”

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 counterpropagating mixing of a steady-state reference wave with a phase-modulated signal wave on reflective holograms in samples of X -cut crystals of symmetry classes 23,43m,42m, 422, 622, 222, and 3m. Experimental studies of such mixing of waves with circular polarization of opposite signs in a Ba 12 TiO 20 :Ni crystal made it possible to estimate its flexoelectric coefficient.

“…Mixing of a strong stationary reference wave and a weak signal wave, carrying information in the form of modulation of its phase, at a photorefractive hologram leads to the phase demodulation effect [5,31]. At a harmonic modulating signal with frequency Ω, the signal-wave intensity at the output face of the crystal can be written in the form of expansion (1) (110)…”

Holographic interferometry methods, based on mixing of a stationary reference light beam and a phase-modulated signal beam at the related perturbations of the dielectric tensor in photosensitive crystals, have been applied to measure material parameters determining the value of these perturbations. Experimental conditions, under which one can distinguish contributions to the mixing from the flexoelectric and electrogyration effects in cubic photorefractive sillenite crystals, are determined, and the necessity of taking into account the contribution from the flexogyration effect is demonstrated.

Рассмотрено применение методов голографической интерферометрии, основанных на взаимодействии стационарного опорного светового пучка с фазово-модулированным сигнальным пучком на создаваемых ими возмущениях диэлектрического тензора в фоточувствительных кристаллах, для измерения материальных параметров, определяющих величину этих возмущений. Определены экспериментальные условия, при которых возможно выделение вкладов во взаимодействие флексоэлектрического и электрогирационного эффектов в кубических фоторефрактивных кристаллах класса силленитов; показана необходимость учета вклада в него эффекта флексогирации. Ключевые слова: адаптивная голографическая интерферометрия, фоточувствительные кристаллы, фоторефрактивный эффект, обратный флексоэлектрический эффект, двухпучковое взаимодействие.
