摘要：

We report a continuous-wave, broadly tunable mid-infrared MgO;PPLN optical parametric oscillator pumped by a fiber amplifier. Using pump tuning with synchronized temperature optimization, we achieve the broadest mode-hop-free (MHF) tuning of idler light over 30 cm(-1). We further use this tunable mid-infrared laser to demonstrate high-resolution absorption spectroscopy of methane across the MHF tuning range. (C) 2012 Optical Society of America
