Paper Abstract

Leveraging Pranalytica's fundamental research into high power and high wallplug efficiency QCL devices and high performance/reliability QCL packaging technologies, we developed several models of turn-key QCL systems for security-related applications. Our tabletop high power system produces, at room temperature, more than 2W of nominally collimated continuous wave radiation at 4.6 μm. Our flashlight-size portable illuminator at 4.6 μm produces over 100 mW average power portable illuminator at 9.6 μm produces more than 20 mW, both with runtime of ~10 hrs. These systems are opening the window of QCL acceptance into real-world security and defense applications. At chip level, we have demonstrated 3W of CW power at room temperature from a single, high reflectivity coated chip.
