Optical parametric oscillator pumped at ~one µm with intracavity mid-IR variation-frequency era in OPGaAsWe report over a femtosecond optical parametric oscillator (OPO) for the deep-infrared (deep-IR) based upon the Kerr-lens-mode-locked Ti:sapphire laser as being the pump resource. By deploying a novel cascaded intracavity arrangement, comprisin… Read More
