Title

Higher-Dimensionality Caustics Owing To Competing Reorientation Of A Liquid Crystal By Laser Beams

Keywords

Liquid crystal; Nonlinear interaction; Pattern formation

Abstract

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