Abstract :
The value of third order nonlinear optical susceptibility (chi<3>) of ternary and quaternary ZnSe-based mixed crystals was extracted from the standard backward degenerate four wave mixing (DFWM) measurement at 532 nm. The studied crystals were grown by the modified high-pressure Bridgman method. We found that the value of third order nonlinear optical susceptibility (chi<3>) for Zn0.79Be0.21Se is higher than that for Zn0.80Mg0.20Se. We also found that the value of chi<3> for Zn0.83Be0.04Mg0.13Se is located between the values obtained for Zn0.79Be0.21Se and Zn0.80Mg0.20Se.
