Abstract
We present experimental results on the propagation of an interference pattern of two He-Ne laser beams of unequal amplitudes through a photo refractive Bi12TiO20 crystal in the presence of drift nonlinearity. Th e phenomenon that we have observed is the focusing of the fringes as t he nonlinearity of the crystal is increased. We show that such a pheno menon can be quantitatively interpreted in the framework of modulation instability theory. (C) 1995 Optical Society of America
