Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR change-frequency generation in OPGaAs We report over a femtosecond optical parametric oscillator (OPO) with the deep-infrared (deep-IR) dependant on the Kerr-lens-method-locked Ti:sapphire laser given that the pump supply. By deploying a novel cascaded intracavity arrangement… Read More
