TL;DR: In this article, a theoretical study of the polarization dependence of stimulated Rayleigh-wing scattering and the optical-frequency Kerr effect has been undertaken, and the results can be immediately generalized to any light scattering process of tensor symmetry.
Abstract: A theoretical study of the polarization dependence of stimulated Rayleigh-wing scattering and the optical-frequency Kerr effect has been undertaken. When the incident light is circularly polarized, a striking difference in gain is found for the co- and counter-rotating senses of polarization of the scattered light---the former being suppressed and the latter being exceptionally favored. The analysis begins with a model for the Kerr effect, which involves the alignment of anisotropic molecules in an electric field, but the results can be immediately generalized to any light scattering process of tensor symmetry. The nonlinear problem of the propagation of an intense elliptically polarized light wave in a Kerr-active medium is shown to have a solution in which the vibrational ellipse undergoes self-precession and self-retardation. The stimulated scatterings or instabilities of such a self-precessing and self-retarding light wave are obtained for the backward and forward directions. Birefringence, optical activity, and linear and circular dichroisms are some of the phenomena which result, but the forward direction yields substantially different results from the backward direction because of Stokes-anti-Stokes coupling.

TL;DR: This chapter discusses the optical rotatory dispersion and circular dichroism, which can be regarded to be made up of two equal, but opposite, circularly polarized components, one left- handed (lcp) and one right-handed (rep).
Abstract: Publisher Summary This chapter discusses the optical rotatory dispersion and circular dichroism A linearly polarized light can be regarded to be made up of two equal, but opposite, circularly polarized components, one left-handed (lcp) and one right-handed (rep) On passing through an optically inactive medium, the speeds of both components are equally affected, so the plane of polarization remains unchanged upon recombination But in an optically active medium, the speeds of the two components are unequally influenced, so the emergent light rotates through an angle with the plane of polarization of the incident light The presence or absence of circular dichroism (CD) can also be studied with linearly polarized light If the left and right circularly polarized components of a linearly polarized beam are absorbed equally, the emergent light remains linearly polarized If, however, the two components are absorbed unequally, the resultant field no longer oscillates along a single line, and the head of the recombined components traces an ellipse

TL;DR: In this article, a container of fluid is placed in the path of a polarized light beam, and the polarization of the light is changed an amount dependent upon the effective dimensions of the container and the optical properties of the fluid.
Abstract: The electrical control of light polarization utilizing the optical properties of fluids. A container of fluid is placed in the path of a polarized light beam, and the polarization of the light is changed an amount dependent upon the effective dimensions of the container and the optical characteristics of the fluid. Means responsive to the change in polarization are included for either deflecting, or varying the intensity of, the polarized light.
