BWOs reach 2.22 THz
Backward Wave Oscillators (BWOs) have been used for THz spectroscopy and imaging across 0.03-1.5 THz range for decades. Recent progress in solid-state multiplier technology enabled efficient frequency doubling and tripling of BWO output to extend their reach beyond 1.5 THz. One of the latest examples of this approach is combining QS1-710 (OV-80) BWO operating across 550-720 GHz with a frequency tripler produced THz output across 1.8-2.22 THz range. Detailed report on progress in performance of BWOs combined with solid-state multipliers will be presented at the Photonics West conference in San Francisco on January 24th: http://spie.org//app/program/index.cfm?fuseaction=conferencedetail&conference=7601
This BWO and tripler combination is now available as a product called QS1-710-T. While output power reaches only 0.02 mW, it is actually sufficient to get 3 orders of magnitude in signal to noise ratio using amplified Golay Cell as a detector.
