In this study, to realize practical and high-quality mid-infrared dual-comb spectroscopy, a mechanical-sharing dual-comb fiber laser based on a low-noise mode-locking mechanism with improved passive stability was developed, and mid-infrared light was generated. By constructing a dual-comb interferometer with the broadband mid-infrared light, clear interferogram were obtained across the entire spectral bandwidth. These results demonstrate that the developed broadband mid-infrared frequency comb possesses sufficient relative coherence for dual-comb spectroscopy.
