Paper Abstract

Using single-defect single band mode, a large value of the exponential gain coefficient is obtained by degenerate two- picosecond light pulses in a photorefractive GaAs:EL2 crystal in the presence of an applied magneto-static field. The influences of a cd magnetic field on the temporal recording and erasure of the grating are analytically analyzed. A significant enhancement of the diffraction efficiency of the recorded hologram by a factor of 2 is obtained. The results are good qualitatively in agreement with the experimental observations.
