NOT KNOWN FACTS ABOUT HGGA2S4 CRYSTAL

Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR difference-frequency era in OPGaAsWe report with a femtosecond optical parametric oscillator (OPO) for your deep-infrared (deep-IR) depending on the Kerr-lens-manner-locked Ti:sapphire laser as the pump supply. By deploying a novel cascaded intracavity arrangement, comprising a
