Abstract

Quantum cascade lasers are finding rapid acceptance in many defense and security applications. Our new multispectral laser platform providing watt-level outputs near 2.0 μm, 4.0 μm and 4.6 μm in continuous wave regime at room temperature. Individual lasers are spectrally beam combined into a single output beam with excellent quality. Our rugged, compact (11 × 10 × 6.5 inches), and highly reliable, air-cooled multispectral laser platform is already finding acceptance at system level. Our uncooled devices produce > 2W at 4.6 μm and >1.5W at 4.0 μm at room temperature, and maintain watt-level output at 67°C with real wallplug efficiencies >10%. Finally, all of our QCLs undergo 100-hour pre-delivery burn-in and pass shock, vibration, and temperature testing according to MIL-STD-810G.
