Abstract. Investigated in this work is the influence of two-photon absorption on the major semiaxis angle rotation, ellipticity, focal parameter and eccentricity of polarization ellipse of light traveling in uniaxial single crystals. Influence of pumping intensity, angle of phase lag, coefficients of one-photon and two-photon absorption on polarization of light propagating in CdS single crystal is studied. Lasers, with the steady-state temperature of active body, which generate the pulse nanosecond duration and 0.1 pm line width radiation or lasers that generate the pulse with duration less than 300 fs are necessary to be used. The criteria to choose semiconductor parameters for providing optimum conditions for researches of light polarization at presence of two-photon absorption are formulated.
Keywords: CdS, two-photon absorption, ellipticity, ellipse of polarization.
