LITTLE KNOWN FACTS ABOUT HGGA2S4 CRYSTAL.

Optical parametric oscillator pumped at ~one µm with intracavity mid-IR variation-frequency era in OPGaAsWe report with a femtosecond optical parametric oscillator (OPO) for the deep-infrared (deep-IR) according to the Kerr-lens-manner-locked Ti:sapphire laser because the pump resource. By deploying a novel cascaded intracavity arrangement, compri
