Abstract

Stimulated Orientational Scattering (SOS) uses the angular reorientation of the director axis in liquid crystals to produce cross-polarized light amplification. Akin to photorefractivity, SOS uses grating formation and the resulting phase-matching to scatter incident radiation into a coherent, cross-polarized signal beam. This paper provides a brief review of the theory underlying SOS, a discussion of the simulation of SOS dynamics, and empirical results of the SOS effect acting in a thin film (300 μm) planar sample of the liquid crystal E7 induced by an Argon ion laser at a wavelength of 488 nm.
