The nonlinear optical characteristics of AgGaS2 were investigated by measuring visible parametric fluorescence with a pump wavelength of 600 nm. A value of d36 [AgGaS2] = 31 ± 5 10-12 m/V for the nonlinear coefficient was determined. The temperature dependence of phase matching up to 100 °C was studied. A significant temperature effect, although much smaller than for LiNb03, was found and results in a change in the infrared difference frequency generated of ∼ 0. 6 cm-1. °c-1.
