Abstract.

A 2.2-W continuous-wave, continuously tunable, single-frequency OPO has been developed in the 3.0–3.8 μm wavelength range for the detection of molecular trace gasses. The oscillation threshold, output power and stability of the single resonant OPO were improved by optimizing pump beam waist and OPO cavity length. Both air-spaced and solid etalons were tested to frequency stabilize and tune the OPO, from which the solid etalon gave a better performance. Temperature oscillations in the PPLN crystal caused oscillations in the idler wavelength of less than 200 MHz over 300 s; the short-term stability was less than 3 MHz over 1 s. The high laser power, in combination with photoacoustic spectroscopy, achieved a detection limit of 10 parts-per-trillion for ethane in nitrogen.
