We report on a slowing down of light pulses using degenerate backward-wave four-wave
mixing in a photorefractive crystal. The delay and width of the output pulse for the amplified …

Slowdown of Gaussian “dark pulses” in photorefractive crystal using a two-wave mixing
method is shown at room temperature. In agreement with our theoretical model, the …

The slowing down of light pulses with backward-wave four-wave mixing is analyzed for
photorefractive crystals with different coupling strengths. The conditions are found for which …

We study here the four-wave mixing in photorefractive crystals with light beams of partial
temporal coherence. We consider the evolution of the mutual coherence of the beams due to …

By applying pulsed electric fields to photorefractive crystals, the two-wave mixing gain is
considerably increased. Unlike other enhancement techniques, the maximum gain is not …

We show theoretically that the group velocity of light pulses can be reduced significantly by
use of the steep dispersion properties of the phase coupling effect in the photorefractive two …

The ability to delay short light pulses is a promising solution for all-optical
telecommunications, but suffers from a large distortion of the delayed pulse as a …

The temporal behavior of the self-pumped phase conjugation in a photorefractive crystal
with a variety of forms of the seed is carefully studied using a two-dimensional model which …
