In this work, parametric interaction is investigated with the account for phase change of interacting pump, signal and idler waves in the materials of infrared (IR) range of spectrum in case of Zn 1-x Mg x Se crystal. We give an analysis of the threshold intensity of pumping for Zn 0.75 Mg 0.25 Se crystal under conditions of the existing experiment, as well as the analytical expression for obtaining the optimum value of phase mismatch Δopt, at which maximum of signal wave reinforcement is reached. The values of refractive indices, angle of phase matching and angular dispersion coefficient of the first-order for Zn 0.52 Mg 0.48 Se have been calculated.

This paper analyzes a highly efficient broadband second-harmonic generator in the mid infrared region using an isotropic reverse tapered semiconductor slab configuration, using fractional total internal reflection quasi-phase matching technique. A computer aided simulation has been performed using ZnTe as the nonlinear material which provides an extremely high conversion efficiency of 22.94% with a 3[Formula: see text]dB bandwidth of 200[Formula: see text]nm. Effect of varying the slab dimensions on the performance parameters has also been analyzed. Finally, the catastrophic effect caused by destructive interference due to nonlinear law of reflection has also been incorporated in the analysis thereby giving more accurate results.
