Abstract

Room-temperature Quantum Cascade Lasers (QCL) allow high-sensitivity measurements of trace gas absorption in the 4.6 to 11 micron wavelength region. Important combustion-generated pollutants such as CO and NO exhibit strong fundamental absorption bands in this region and sub-ppm detection limits are projected. The paper will present initial results for both species obtained in a laboratory flat flame burner.
