Abstract

We report the first application of a thermoelectrically cooled, distributed–feedback quantum–cascade laser for continuous spectroscopic monitoring of CO in ambient air at a wavelength of 4.6 μm. A noiseequivalent detection limit of 12 parts per billion was demonstrated experimentally with a 102–cm optical pathlength and a 2.5–min data acquisition time at a 10–kHz pulsed–laser repetition rate. This sensitivity corresponds to a standard error in fractional absorbance of 3 × 10^-5.
