Abstract

The application of cw and pulsed single-frequency QC-DFB lasers to the sensitive detection of CH4, N2O, C2H5OH (ethanol) and different isotopic species of H2O in ambient air is discussed. Using a new approach based on a linear correlation technique, the ethanol concentration from its dense infrared spectrum is determined.
