New type of fluorophosphate glasses with different Tm 3+/Ho 3+ doping concentrations have
been prepared. From the measured fluorescence spectra, strong emission near 2 μm is …

Phenomena that accompany optical excitation of eigenmodes of electron gas oscillation in
semiconductors with an N-shaped current-voltage (IU) characteristic in a strong electric field …

We investigate the dispersion law (relationship between Ω k and K) of photorefractive waves
using a new experimental method based on the excitation of photorefractive waves by a …

The signal-to-noise ratio of the output of an adaptive holographic interferometer (AHI) based
on a Bi_12TiO_20 crystal is investigated. We show experimentally that the sensitivity of an …

A theory is proposed to describe holograms in thin photorefractive crystals and the self-
diffraction of two writing laser beams, one of which is periodically modulated in phase. In …

The theory of grating oscillations in photorefractive materials is developed in the linear and
nonlinear approximations for the drift mechanism of holographic recording. The resonance …

Рассмотрена теория явлений, возникающих при оптическом методе возбуждения
собственных мод колебаний электронного газа в полупроводниках с падающим …

We report an optoelectronic feedback loop suitable for generating noise-free interference
patterns oscillating at arbitrary waveforms. The technique allows controlling the frequency …

Resonant optical excitation of surface waves of a photorefractive crystal (BSO) was
observed for the first time when a hologram was recorded by an oscillating interference …

Предложена теория записи голограмм в тонких фоторефрактивных кристаллах и
самодифракции двух записывающих лазерных лучей, один из которых периодически …
