Photocatalysis has been widely studied for environmental applications and water treatment
as one of the advanced oxidation processes (AOPs). Among semiconductors that have been …

Sillenite materials have been the subject of intense investigation for recent years due to their
unique characteristics. They possess a distinct structure with space group I23, allowing them …

Photorefractive materials combine photoconductive and electro-optic properties: light affects
their electrical conductivity; their optical properties (refractive index, etc.) are affected by …

Heterodyne interferometers using two‐wave mixing in photorefractive cubic crystals for
ultrasound detection on rough surfaces are demonstrated. The speckled scattered beam …

We consider in detail the piezoelectric properties and the optical activity of (110)-cut cubic
photorefractive crystals with respect to the optimization of two-beam coupling. An expression …

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 …

A holographic interferometer that uses two-wave mixing in a photorefractive (Bi_12SiO_20)
crystal under an applied ac field is described. The interferometer uses a repetitive sequence …

The influence of optical activity on two-wave mixing (TWM) in photorefractive BTO and BSO
crystals in the absence of an applied field is studied both theoretically and experimentally …

A three-dimensional model describing two-wave mixing in photorefractive crystals with finite
beams of arbitrary shape is presented. The well-known longitudinal and transverse …

Дан обзор развития теоретических и экспериментальных основ фоторефрактивного
эффекта в кубических гиротропных пьезокристаллах. Показано, что влияние обратного …
