Abstract: In the present work the results of investigations of the influence of different parameters on conversion efficiency in mixed Zn1-xMgxSe crystal in conditions of existing experiments are cited. The comparison of the obtained results on conversion efficiency with the analogous experimentally measured values has been made. The results of calculation of the angles of phase matching and angular dispersion coefficients for Zn0.52Mg0.48Se crystal on wavelengths of the IR range are cited. The angular dispersion coefficients for Zn1-xMgxSe have been calculated. The angular width of phase matching has been estimated.Abstract: In the present work the results of investigations of the influence of different parameters on conversion efficiency in mixed Zn1-xMgxSe crystal in conditions of existing experiments are cited.
