Abstract

We present new experimental results for the phase-matching properties of the recently discovered BaGa₂GeSe₆ crystal for harmonic generation of a Nd:YAG laser-pumped KTP OPO and a CO₂ laser in the 0.778-10.5910 μm spectral 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 SHG of a CO₂ laser at 10.5910 μm and a 1.85 μm-pumped OPO in the 2.156-3.220 μm and 4.348-13.035 μm spectral ranges.
