… Our analysis indicates that this modulation instability growth rate is identical to the modulation
instability growth rate studied previously in biased photorefractive-nonphotovoltaic crystals …

… modulation instability of broad optical beams in biased photorefractive-photovoltaic crystals
… In this Letter, we investigate the modulation instability of broad (quasi-plane-wave) optical …

… We study numerically the counterpropagating vector solitons in SBN:60 photorefractive
crystals. A simple theory is provided for explaining the symmetry-breaking transverse instability of …

… A non-linear medium, like a photorefractive crystal with non-zero response time, is placed
inside a low-finesse ring cavity having the coherence time much shorter than the time required …

… of the modulational instability of quasi-plane-wave beams in the self-defocusing photorefractive
crystal LiNbO3:Fe. Our analysis shows that this modulational instability is ascribable to …

… the effects of the external field (EF) in a photorefractive crystal. To do so, we use the coupled
… We pointed out the effects of EF on the modulation instability growth rate. Throughout the …

… are of the attraction features of photorefractive (PR) materials. … illuminated region of
photorefractive crystal can also change … On the other hand, modulation instability (MI) in a …
