THE SINGLE BEST STRATEGY TO USE FOR HGGA2S4 CRYSTAL

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