LITTLE KNOWN FACTS ABOUT HGGA2S4 CRYSTAL.

Optical parametric oscillator pumped at ~one µm with intracavity mid-IR difference-frequency era in OPGaAsThe importance on the obtained results lies in The reality that to get the identical conversion in SHG or DFM, 1 now needs elementary input radiation with Significantly reduce intensity.Apart from the compactness and benign working functions,
