Abstract

The conditions of high gain in wave mixing experiments with moving gratings in photorefractive BSO crystals are reviewed. It is shown that under optimum recording conditions the photoinduced grating is phase shifted by π/2 while the amplitude of the space charge field is increased. Efficient interactions in wave mixing experiments are thus obtained with demonstrated applications to image amplification, phase conjugation with gain and different types of oscillations. These oscillations result from self-induced moving gratings in BSO.
