Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR big difference-frequency generation in OPGaAsWe report over a femtosecond optical parametric oscillator (OPO) for that deep-infrared (deep-IR) based upon the Kerr-lens-manner-locked Ti:sapphire laser given that the pump resource. By deploying a novel cascaded intracavity arrange
