abstract = "We present recent results on development of swept external cavity quantum cascade lasers (ECQCLs) for rapid and precise measurements of trace gases. Rapid tuning of a swept-ECQCL over its entire tuning range at rates up to 100 Hz and a spectral resolution of <0.2 cm-1 provides an important capability for detection of gas mixtures in transient sources such as chemical plumes. We present examples of using the swept-ECQCL for quantitative measurements of multicomponent gas-phase mixtures in turbulent plumes for standoff detection applications.",
