title = "High power, widely tunable, and beam steerable mid-infrared quantum cascade lasers",
abstract = "After more than 20 years of development, quantum cascade lasers (QCLs) have become the leading laser source emitting in the mid-infrared spectrum region between 3 and 12μm, where CBRN and explosives have strong absorption signatures. The Center for Quantum Devices at Northwestern University currently holds the record for both the highest room temperature continuous wave output power of 5.1 W and the most efficient QCL of 53% wall plug efficiency operating at cryogenic temperature. This book chapter presents our latest development results on mid-infrared QCLs with wavelength tuning and high power beam steering capabilities, which significantly enhances QCL{\textquoteright}s suitability for remote spectroscopy and sensing applications.",
