Optical properties and nonlinearity on phase-matching (PM) of two (yellow and orange) phase HgGa_(2)S_(4) crystals were investigated in details. Damage threshold was determined in comparison with middle infrared (IR) crystal at identical experimental conditions. Second harmonic generation (SHG) of 30 ns TEA CO2 laser pulses was realized with 5% efficiency in energy and 6.9% in peak power.
