Demonstration and frequency noise characterization of a 17 m quantum cascade laser
M Manceau, T E Wall, H Philip +5
We evaluate the spectral performance of a novel continuous-wave room-temperature distributed feedback quantum cascade laser operating at the long wavelength of 17 m. By demonst…
Extending frequency metrology to increasingly complex molecules: SI-traceable sub-Doppler mid-IR spectroscopy of trioxane
Dang Bao An Tran, Mathieu Manceau, Olivier Lopez +3
Bringing increasingly complex polyatomic molecules within reach of precision measurement experiments offers fascinating and far-reaching prospects ranging from Earth sciences and a…
Wavelength modulation laser spectroscopy of NO at 17 m
Y. Wang, J. Rodewald, O. Lopez +4
Using a mid-infrared quantum cascade laser and wavelength modulation absorption spectroscopy, we measure the frequencies of ro-vibrational transitions of NO in the 17 m reg…
Near-to mid-IR spectral purity transfer with a tunable frequency comb: methanol frequency metrology over a record frequency span
D B A Tran, Olivier Lopez, M Manceau +8
We report the upgrade and operation of a frequency-comb-assisted high-resolution mid-infrared molecular spectrometer allowing us to combine high spectral purity, SI-traceability, w…
