    Abstract

    The optical controlling reflection and the optical limiting effect realized in ZnS/ZnSe nonlinear stratified waveguide grating is reported in this paper, and the deflective angle of the second order Bragg diffraction was about -2° and the change of refractive index was about -0.049 at Ar+ laser optical intensity of 2.60×105 W/cm2. The refractive index coefficient of the material obtained was -1.9×10-7 cm2/W, which accords with the value reported by the foreigner. The nonlinear threshold of the optical limiting was about 140 mW, the limiting amplitude threshold was 24 mW.
