Abstract

Dual-wavelength DFB-QCLs are promising light sources for multi-species laser absorption spectrometers. We demonstrate the combination of several dual-wavelength QCLs to measure concentrations of the most important pollutants and green-house gases in a compact laser spectrometer with state-of-the-art precision.
