Abstract :
Using two-waves mixing of pico-second pulses in photorefractive-crystal, the role of the magneto-static field on photorefractive parameters is analyzed. It is found that magnetic-field plays a crucial role near the resonance condition when time delay is order of recombination time and diffraction efficiency of recorded hologram can be significantly enhanced.
