The photorefractive recording dynamics of two-beam coupling in semi-insulating
semiconductors by beams with slightly different frequencies are studied theoretically and …

We describe how two-wave mixing of light scattered at the entrance face of a photorefractive
crystal can be used to measure the frequency difference between two independent lasers …

We describe a new method for photorefractive response time measurement in fast
photorefractive crystals based on continuous phase modulation in two-wave mixing. We …

We demonstrate that two-wave mixing of partially coherent light beams inside a medium with
an inertial nonlinear response allows one to increase the coherence substantially. An …

The photorefractive effect is an extremely versatile nonlinear mechanism for parallel optical
processing. Applications such as image amplification, real-time interferometry, convolution …

We describe how optical beams from a mode-locked laser will couple in a photorefractive
crystal. We show that the two-beam-coupling gain coefficient is proportional to the square of …

A simple polarization technique for separate measurement of absorption and phase gratings
in photorefractive crystals, that allowed us to demonstrate experimental evidence of …

Semiconductors as photorefractive materials sensitive to infrared light are among others
advantageous since they have small response times. Typically these time constants are in …
