Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR variation-frequency technology in OPGaAsWe report on a femtosecond optical parametric oscillator (OPO) for that deep-infrared (deep-IR) dependant on the Kerr-lens-mode-locked Ti:sapphire laser because the pump resource. By deploying a novel cascaded intracavity arrangement, comp… Read More
