Abstract

A novel difference-frequency mixing architecture for coherent generation of tunable mid-infrared light is reported. Two CW single-frequency diode laser pump sources operating at 1.56 and 0.98 µm were mixed in a periodically poled LiNbO3 crystal and generated 0.25 mW of tunable mid-infrared light at 2.64 µm. The performance of this new source was demonstrated by the spectroscopic detection of HF and water isotopes H216,17,18 O and HD16O at various reduced pressures. Using direct absorption spectroscopy, a peak-to-peak noise equivalent absorbance of ~1E-4 was observed (0.6 s integration time), corresponding to a HF detection sensitivity of 12 ppb.m at a sampling pressure of 50 Torr.
