Optical parametric oscillator pumped at ~one µm with intracavity mid-IR change-frequency technology in OPGaAsWe report on a femtosecond optical parametric oscillator (OPO) to the deep-infrared (deep-IR) dependant on the Kerr-lens-mode-locked Ti:sapphire laser as the pump supply. By deploying a novel cascaded intracavity arrangement, comprising a f… Read More
