Mid-infrared (MIR) spectrometers are invaluable tools for molecular fingerprinting and imaging. Among the available spectroscopic approaches, MIR dual-comb absorption spectrometers have the potential to simultaneously combine the high-speed, high spectral

Broad bandwidth mid-infrared frequency combs are important for molecular spectroscopy in a wide range of fundamental and applied research. However, realization of such light sources in a compact and robust format remains a challenge. In this paper, we

We demonstrate the application of mode-locked mid-infrared dual frequency comb spectroscopy for combustion analysis. With two settings of the same dual-comb system, the measurement spans 1500 cm-1 (2.8 to 5 microns) with 0.0067 cm-1 (200 MHz) point spacing
