We propose to develop new quantum cascade-laser (QCL) based systems useful for military platform and perimeter protection, free space communications, infrared countermeasures, and chemical sensing applications. New QCL structures will be designed and optimized, and a careful thermal analysis will be performed to determine cooler requirements and the best cooler design for a system operating at or near room temperature in the LWIR (8.5 - 12 micron) wavelength band producing on the order of 0.5 W average power at a 25% duty cycle. Various laser configurations will be investigated, including a master oscillator/power amplifier (MOPA) configuration with a QCL-based oscillator chip coupled to a grating to form an external cavity laser that provides a tunable source of nearly monochromatic light to a QCL-based semiconductor optical amplifier chip.
