Quantum cascade lasers operating in the 3.5 to 24 micron spectral range can be used for trace gas detection in ambient air based on absorption spectroscopy. Recent advances in spectroscopic detection techniques have been employed to achieve minimum detectable absorption coefficients of 10/sup -9/ cm/sup -1/ in several real world applications.
