Efficient High Power THz laser

The emerging field of terahertz imaging and spectroscopy offers great promise in physical security, military, drug enforcement and pharmaceuticals. Progress in THz applications awaits development of a high power THz laser, and a fast, sensitive focal plane array. Both of these are under development at Zyberwear. This work proposed here is development of a new class of laser operating at terahertz wavelengths. Existing THz lasers are capable of several watt output in a mixed-mode (broadband) operation, but at very low efficiencies. The proposed laser is projected to have a power output in excess of 10 W, an electrical to optical efficiency approaching 1%, and a very low noise, stable, narrowband, tunable, low divergence output beam.
