Abstract

This manuscript describes the design of a robust, mode-locked laser based, mid-infrared dual- comb spectrometer operating in the 3.1-µm to 4-µm spectral window. The design represents an improvement in signal-to-noise, system size, power consumption and robustness relative to previous work and should be a viable platform to investigate future mid-infrared dual-comb applications in the field. System quality factors of 2×10^6 and 30 hours of continuous operation are demonstrated over a 120-meter outdoor air path
