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