Abstract
We present our latest results on the development of Quantum Cascade Lasers with Watt-level output power in the mid-wave infrared (MWIR) and long-wave infrared (LWIR) spectral regions. Wall-plug efficiencies in excess of 10% and 5% at 1 W output power level at room temperature were demonstrated at wavelengths of 4.0 and 9.0 µm, respectively. A ruggedized packaging which is capable of withstanding environmental conditions including mechanical shocks, vibrations, extreme storage temperature excursions, extreme ambient temperature excursions during operation, and thermal shocks was developed and qualified.
