Abstract

Novel pulsed and cw quantum cascade distributed feedback (QC-DFB) lasers operating near λ = 8 μm were used for detection and quantification of trace gases in ambient air by means of sensitive absorption spectroscopy. N₂O, ¹²CH₄, ¹³CH₄, and different isotopic species of H₂O were detected. Also, a highly selective detection of ethanol vapor in air with a sensitivity of 125 parts per billion by volume (ppb) was demonstrated.
