We evaluate two designs of dual-wavelength DFB-QCLs for high-resolution multi-species laser absorption spectrometers. Several room-temperature dual-wavelength QCLs were combined to measure concentrations of the most important pollutants and greenhouse gases in a compact laser spectrometer with state-of-the-art precision.
