NOT KNOWN FACTS ABOUT HGGA2S4 CRYSTAL

Optical parametric oscillator pumped at ~one µm with intracavity mid-IR difference-frequency technology in OPGaAsWe report over a femtosecond optical parametric oscillator (OPO) for your deep-infrared (deep-IR) determined by the Kerr-lens-mode-locked Ti:sapphire laser as being the pump source. By deploying a novel cascaded intracavity arrangement,
