Recent advances of trace gas sensors based on diode and quantum cascade lasers

Diode and quantum cascade lasers can be used for trace gas detection in ambient air based on absorption and photoacoustic spectroscopy. Advances in spectroscopic detection techniques have resulted in minimum detectable absorbances of 10/sup -5/ in several applications.
