We report new experimental results on the phase-matching properties of AgGa_0.86In_0.14S₂ for second-harmonic generation (SHG) and sum-frequency generation (SFG) of a Nd:YAG laser-pumped KTiOPO₄ (KTP), AgGaS₂ optical parametric oscillators (OPOs), and a CO₂ 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 d₃₆(AgGa_0.86In_0.14S₂) = 13.4 pm/V measured by SHG method.

AgGa0.86In0.14S2 在 0.615−10.5910 µm 光谱范围内三波相互作用的相位匹配特性

我们报告了 AgGa _0.86 In _0.14 S ₂的相位匹配特性的新实验结果，用于 Nd:YAG 激光泵浦 KTiOPO ₄ (KTP)、AgGaS _{2 的}二次谐波生成 (SHG) 和和频生成 (SFG)光学参量振荡器 (OPO) 和0.615-10.5910 µm 光谱范围内的 CO ₂激光器。此外，我们提出了 Sellmeier 方程，该方程很好地再现了当前的实验结果和非线性光学常数 d ₃₆ (AgGa _0.86 In _0.14 S ₂ ) = 13.4 pm/V 的值，通过 SHG 方法测量。
