NOT KNOWN DETAILS ABOUT HGGA2S4 CRYSTAL

Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR difference-frequency technology in OPGaAsWe report with a femtosecond optical parametric oscillator (OPO) for your deep-infrared (deep-IR) dependant on the Kerr-lens-mode-locked Ti:sapphire laser given that the pump source. By deploying a novel cascaded intracavity arrangement,
