摘要：

We demonstrate dual-comb spectroscopy in the vicinity 2 mu m wavelength based on a single dual wavelength dual-comb Thulium-doped fiber laser. The shared laser cavity ensures passively maintained mutual coherence between the two combs due to common mode environmental noise rejection. In a proof-of-principle experiment, the absorption characteristics caused by the water in the optical path that composes the dual-comb spectrometer are measured. The retrieved spectral positions of the water absorption dips match with the HITRAN database. (C) 2018 Optical Society of America under the terms of the OSA Open Access Publishing Agreement.
