Abstract: In the present work, parametric interaction is considered when the phase change of interacting pump, signal and idler waves is studied in the materials of mid-infrared range of spectrum for GaSxSe1-x crystals. The values of refractive indices, angle of phase matching and angular dispersion coefficient of the first order have been calculated for GaS0.4Se0.6 crystal. It was shown that GaS0.4Se0.6 compound could be used for nanosecond/picoseconds pumping of optical parametric converters at 1.064 mcm (Nd:YAG laser systems) without considering two-photon absorption
