Abstract
I will describe recent developments of continuous wave, room temperature (CW/RT) high power QCLs at wavelengths < 3.8 μm to > 12 μm. QCLs now provide, on a commercial basis, CW/RT power of over 3 W at 4.6 μm, with a wall plug efficiency of over 15%, over 2 W at 4.0 μm, and over 1.2 W at 7.1 μm, with a wallplug efficiency >8%. I will describe insertion of QCLs into applications including MWIR countermeasures (IRCM), MWIR and LWIR target illuminators and designators, MWIR beacons (IFF), test equipment for measuring the efficacy of IRCM and sources for MWIR and LWIR radiation for detection of chemical warfare agents and explosives.
