Over the past few years, quantum cascade lasers (QCL) have evolved from scientific curiosities to enablers of commercial instruments, providing sensing, detection, and molecular spectroscopy. Here you’ll find discussions ranging from the basic physics of QCL core technology to system level applications. Topics include stand-off explosive detection, distributed sensor networks, trace gas analysis, ring resonators and waveguides, as well as in vitro glucose detection, and mid-IR imaging. Feel free to review and download information of interest from this growing pool of resources.
