Introduction. Acousto-optic spectrum analyzers interferometric schemes have been developed to increase dynamic range. It was assumed that dynamic range, expressed in dB, would double. An expected increase was not achieved yet.Aim. To analyze the homo

We established that for anisotropic Bragg light diffraction on holographic phase gratings for significant perturbation amplitudes of the refractive index of the medium, in the transmitted diffraction orders there is a significant rotation of the pola

The diffraction of light by reflective holographic gratings in a layer placed between the coating and the substrate having refractive indices different from the average refractive index of the inserted layer is investigated. Significant differences b

Noncollinear triple acousto-optic diffraction of Bessel light beams by ultrasound in uniaxial crystals is investigated. An expression for the complex vector amplitude of a wave diffracted under exact Bragg synchronism conditions is obtained in vector

The acousto-optical Bragg diffraction of Bessel light beams on dispersion Lave waves in a multilayer air-SiO2-Si system was studied as a function of the ultrasonic wave deformation amplitude for layer thicknesses corresponding to the first four Lave

The noncollinear acousto-optic filtration of infrared region Bessel light beams in uniaxial crystals has been investigated. An expression is found for the diffraction efficiency depending on the parameters of the interacting Bessel beams of the o- an

Noncollinear double acousto-optical diffraction of Bessel light beams on ultrasound in uniaxial gyrotropic crystals is studied theoretically and experimentally. It is found that when a Bessel light beam propagates along the optic axis of a crystal, t

We have studied the features of noncollinear acousto-optic filtering of quasi-nondiffracting Bessel light beams in uniaxial crystals. We have obtained coupled wave equations for the vector amplitudes of an incident ordinary (o-type) Bessel beam and a
