Abstract

We have observed stimulated extraordinary–ordinary wave scattering and cross-polarized self-starting optical phase conjugation effects in a nematic liquid-crystal film. The basic mechanism involved is the nonresonant laser-induced nematic crystal axis reorientation. These processes require low optical power and are characterized by millisecond response speed.
