Abstract
We report the rapid tuning of mid-infrared waves beyond emitted in difference-frequency mixing with an electronically tuned dual-wavelength laser used as a pumping source. Simultaneous rapid tuning of the dual wavelengths, which satisfy phase matching in , allows rapid random access switching and continuous tuning of mid-infrared wavelengths. In random-access switching, the mid-infrared wavelength is tuned every pulse shot at a repetition rate of . Mid-infrared wavelengths continuously tuned from , from , and from are achieved at phase-matched angles of 55°, 50°, and 45°, respectively.
