title: Phase-matching properties of yellow color HgGa2S4for SHG and SFG in the 0.944-10.5910  μm range.
abstract: We report new experimental results on the phase-matching properties of yellow color HgGa2S4crystals for harmonic generation of an Nd:YAG laser-pumped KTiOPO4(KTP) optical parametric oscillator (OPO) and CO2lasers in the 0.944-10.5910 μm range. In addition, we present new Sellmeier equations that provide a good reproduction of the present experimental results as well as the published data points for second-harmonic generation of CO2laser radiation at 9.2197-9.6392 μm and Nd:YAG laser-pumped OPOs at 1.205-1.725 μm and 2.77-9.10 μm that were achieved with the orange and yellow color crystals.
