Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR difference-frequency technology in OPGaAsWe report on a femtosecond optical parametric oscillator (OPO) to the deep-infrared (deep-IR) according to the Kerr-lens-manner-locked Ti:sapphire laser as the pump source. By deploying a novel cascaded intracavity arrangement, comprising
