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