Phase-matching properties of AgGa0.86In0.14S2 for three-wave interactions in the 0.615−10.5910 µm spectral range

We report new experimental results on the phase-matching properties of AgGa 0.86 In 0.14 S 2 for second-harmonic generation (SHG) and sum-frequency generation (SFG) of a Nd:YAG laser-pumped KTiOPO 4 (KTP), AgGaS 2 optical parametric oscillators (OPOs), and a CO 2 laser in the 0.615−10.5910 µm spectral range. In addition, we present Sellmeier equations that provide a good reproduction of the present experimental results and the value of the nonlinear optical constant d 36 (AgGa 0.86 In 0.14 S 2 ) = 13.4 pm/V measured by SHG method.
