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 = 40 о , the minimum value of ellipticity and the maximal values of focal
parameter and eccentricity will be realized.
Keywords: CdS, two-photon absorption, ellipticity, ellipse of polarization.
