Abstract
Mid-IR spectroscopy using QCLs allow sensitive, selective, and fast detection of trace gases. Recent developments in multipass cell design and acquisition electronics permit the construction of rugged and lightweight instruments for field application. This is demonstrated by the successful balloon-borne water vapor measurement in the lower stratosphere with an integrated QCL-based spectrometer.
