The linear and nonlinear optical properties and phase matching of the doped nonlinear crystal Cd0 35Hg0 6 5Ga2 S4 were studied. Under the same experimental conditions, the damage threshold of this crystal was measured in comparison with the known mid-infrared crystal. CO2 laser second harmonic generation experiment, consistent with the theoretical prediction
