CONSIDERATIONS TO KNOW ABOUT HGGA2S4 CRYSTAL

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