Abstract

Recent advances in room-temperature, high average power mid-IR semiconductor laser sources now permit direct absorption measurements of strong, fundamental vibrational transitions of many important combustion species using compact sources. In particular, the Quantum Cascade (QC) laser technology developed by Lucent Technologies has demonstrated sources between 3.4 and 13 μm, including high average power, single-mode devices at selected wavelengths in this range. Here, we report on initial evaluation of QC laser-based sensors for combustion-generated pollutants using absorption near S.4 μm. Absorption sensitivities on the order of 10 ppb-m are demonstrated for NO at room-temperature. Extension of this technology to other combustion-generated pollutant species such as CO and SOx is described.
