Abstract

Block Engineering’s pulsed external-cavity Quantum Cascade Lasers (QCLs) combine the optical brightness of lasers with very broad wavelength tuning to provide a breakthrough capability for spectroscopy. Over the past decade QCLs have been refined, become accepted as a spectroscopy tool, and applied to heretofore challenging sampling scenarios such as transmission through liquids or scattering off of low-reflectivity surfaces. More recent miniaturization of hardware and electronics are now enabling QCLs to become embedded in portable and hand-held instruments. This presentation will briefly review the current state of the art of QCL technology and describe systems recently developed for portable medical diagnostics and hyperspectral imaging.
