The polarization dependence of two-wave mixing for two common crystal orientations is
described and theoretical and experimental results given. The direction of energy exchange …

The structure and dynamics of the four-wave mixing transmission grating in a photorefractive
crystal were investigated. The steady-state grating s amplitude distribution looks like a …

Dependence of the phase conjugate signal in photorefractive four-wave mixing on the
crystal orientation and the polarization of the interacting beams is experimentally studied for …

The photorefractive two-wave mixing gain coefficient Γ of GaAs: Cr and InP: Fe, cut with
different crystallographic orientations, was determined using a cw Nd: YAG (neodymium …

We consider phase conjugation via degenerate four-wave mixing in photorefractive crystals
when more than one grating mechanism is operative. A method for exact solution of the …

Two-wave mixing gain in photorefractive GaAs: Cr using the moving grating technique has
been measured. The results compare well to theory when a value of τ di/τ 2 measured by …

We present measurements of the two-wave mixing gain as a function of frequency detuning
in photorefractive crystals. In many cases, this function is asymmetric, indicating that the …

We have used a 20-kHz ac square-wave electric field to enhance the beam-coupling gain
and the degenerate four-wave mixing reflectivity of photorefractive GaAs at 1.06 μm. The …

It has been demonstratedI-4 that GaAs is a sensitive photorefractive material with the
potential to be used for optical processing in the infrared region. The advantages of using …
