Abstract
Formation of hyperbolic umbilic caustics is observed experimentally in the far-field zone as a result of self- and mutual-phase modulation o f laser beams by means of competing reorientation of a nematic liquid crystal. The interference pattern reveals maximum response for an unus ually small (approximate to 5 degrees) angle of light refraction into the cell. It is thus demonstrated that higher-order diffraction catast rophes can be induced and controlled by nonlinear optical processes. ( C) 1996 Optical Society of America
