“…Its technical details have been provided in previous publications. [28,29] Briefly, the 1064 nm output from a distributed feedback (DFB) diode laser (Toptica, DFB Pro BFY) is amplified in a fiber amplifier (IPG, YAR-10K-1064-LP-SF) to ~10 W and used as the pump beam of the OPO. The output of the DFB is attenuated to 3.5 mW before being fed into the fiber amplifier.…”

We have developed a mid-infrared Doppler-free saturation absorption spectroscopy apparatus using a continuous-wave optical parametric oscillator (CW-OPO). Here we report a comprehensive spectral scan of the Q branch transitions of the ν3=1 band of methane (CH4) with an average line width (FWHM) of 4.5 MHz. The absolute frequency calibration was achieved using previously reported transition frequencies determined using optical frequency combs, while a Fabry-Pérot etalon was used for relative frequency calibration. We report 12 transitions with improved accuracies of ~3 MHz.
