Investigation of light polarization in CdS in the presence of two-photon absorption

Abstract

It is shown that, under the two-photon absorption in CdS, the increase in the azimuth of polarization causes a smooth change of the large semi-axis angle rotation, ellipticity, focal parameter, and eccentricity of the polarization ellipse. When the angle of phase lag δ = 40⁰, the minimum value of ellipticity and the maximal values of focal parameter and eccentricity will be realized.
