Continuous wave operation of quantum cascade lasers is
reported up to a temperature of 312 kelvin. The devices were fabricated as buried heterostructure lasers with high-reflection coatings on both
laser facets, resulting in continuous wave operation with optical
output power ranging from 17 milliwatts at 292 kelvin to 3 milliwatts
at 312 kelvin, at an emission wavelength of 9.1 micrometers. The
results demonstrate the potential of quantum cascade lasers as
continuous wave mid-infrared light sources for high-resolution
spectroscopy, chemical sensing applications, and free-space optical
communication systems.
