The theory of the volume phase holograms in the birefringent electrooptic crystals has been
developed. On the basis of this theory some phenomena experimentally observed in …

A phase grating is produced in an iron-doped lithium niobate photorefractive crystal by two-
beam holographic configuration. Digital holography is used to investigate the two …

The non-linear theory of the self-diffraction on the light induced grating of refractive index in
electrooptic crystals is developed. The intensities of the diffracted beams, the diffraction …

Holographic spectroscopy is highlighted as a powerful tool for the analysis of photosensitive
materials with pronounced alterations of the complex permittivity over a broad range in the …

Photoanisotropic materials make it possible to produce novel optical elements with specific
polarization characteristics. Good examples are polarization holographic gratings (PHG) …

We present experimental evidence indicating the formation of dipolar holographic gratings
in potassium lithium tantalate niobate at the paraelectric phase slightly above the phase …

Oscillating behaviour of diffracted light on uniform illumination of holograms, recorded in
photorefractive crystals Bi 12 TiO 20, is observed experimentally. From the experimental …

We present data on the speed of light‐induced refractive index changes in a BaTiO3 single
crystal. The light‐induced erasure rate of a refractive index grating is shown to depend on …

An analytical time-dependent solution for the light-induced first-harmonic holographic
grating has been obtained for photorefractive materials presenting a bulk photovoltaic (PV) …

In order to obtain the maximum diffraction efficiency, holograms recorded in a
photorefractive crystal must be replayed by a readout beam incident at the correct angle …
