The mid-IR region is ideally suited for absorption spectroscopy since the fundamental vibrational transitions of a number of molecules lie here. Quantum cascade (QC) lasers  fabricated by band structure engineering offer an attractive new option for sensitive IR absorption spectroscopy. Distributed feed-back pulsed QC lasers are of particular interest for they allow the realization of a room temperature, compact IR source with relatively high output power. In particular, their combination with the pulsed-CRDS technique has the potential for high sensitivity trace gas analysis. The goal of our present work is to develop a technique for quantitative online analysis of trace constituents in exhaled breath.  We are using pulsed-CRDS technique in combination with a mid IR QC laser operating near 970 cm-1 to measure ammonia levels in exhaled breath. An unlocked ring-down cavity was designed for these studies which can be operated at atmospheric or reduced pressure. We have already attained a detection limit of 25 ppb for ammonia. We are in a process of improving the system to get down to sub ppb levels with this technique.

Project: Infrared absorption spectroscopy with Quantum cascade laser.The advance of Quantum cascade (QC) lasers fabricated by band structure engineering offers an attractive new option for IR absorption spectroscopy. QC-DFB lasers are of particular interest to gas-sensing applications because they emit single frequency radiation which falls within the 3-15 um window, where the fundamental absorption bands of most of the molecules are located.
