    "abstract": "We present a reliable, narrow linewidth (100 kHz) continuous-wave optical\nparametric oscillator (OPO) suitable for high-resolution spectroscopy\napplications. The OPO is based on a periodically-poled lithium-niobate crystal\nand features a specially designed intracavity etalon which permits its\ncontinuous tuning and stable operation at any desired wavelength in a wide\noperation range. We demonstrate Doppler-free spectroscopy on a rovibrational\ntransition of methane at 3.39 um.",
