WHAT DOES HGGA2S4 CRYSTAL MEAN?

Optical parametric oscillator pumped at ~one µm with intracavity mid-IR variance-frequency technology in OPGaAsWe report over a femtosecond optical parametric oscillator (OPO) with the deep-infrared (deep-IR) based upon the Kerr-lens-mode-locked Ti:sapphire laser given that the pump resource. By deploying a novel cascaded intracavity arrangement,
