Over 200 referred journal articles, application notes & white papers using DRS Daylight Solutions’ QCL-based technologies

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.

If you would like to share your work in mid-IR quantum cascade lasers with others, please send a pdf of your paper or provide a link to [email protected]. We would be pleased to add it to our site for the benefit of all.
