Observation of stimulated orientational scattering and cross-polarized self-starting phase conjugation in a nematic liquid-crystal film.
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.
