The polarization structure of the signal wave that interacts with a circularly polarized pump
wave on the reflection holographic gratings in the (112)-,(111)-, and (110)-cut Bi 12 TiO 20 …

The theoretical analysis of unstationary holographic recording in photorefractive crystals
under an external alternating electric field is presented. In particular, a step-like ac field …

A method for computing the diffraction efficiency of photochromic, transmission holographic
gratings is developed. The nonuniform exposure through the depth of the material is taken …

We explore theoretically and experimentally how application of an electric field to a
photorefractive crystal affects the recording and the readout of holograms. We consider, for …

The idea is well entrenched in the literature that thin phase gratings (whether holographic or
acoustically induced) should exhibit Raman-Nath behavior (and thus give several diffracted …

Holograms are recorded with focused beams in an iron-doped lithium niobate crystal. The
diffraction efficiency shows a maximum after several seconds of recording, unlike in the case …

In this paper we present and demonstrate a technique that allows simultaneous and
independent measurement of small changes in the refractive index and the absorption …

The description of the formation of thick‐phase holograms over the entire range of
exposures has been accomplished using numerical methods. The internal electric field …

One-dimensional photonic crystals with continuous distribution of the dielectric constant
were fabricated by the use of photopolymer materials and laser holography. The angular …

It is shown that reflection grating in [111] Bi 12 TiO 20 crystal can be used for dynamic
interferometry with a low power HeNe laser, giving a diffraction efficiency of 0.14 …
