Abstract

We report the rapid tuning of mid-infrared waves beyond 5 μ m emitted in difference-frequency mixing with an electronically tuned dual-wavelength Ti : Al 2 O 3 laser used as a pumping source. Simultaneous rapid tuning of the dual wavelengths, which satisfy phase matching in Ag Ga S 2 , 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 1 kHz . Mid-infrared wavelengths continuously tuned from 5.2 to 7.2 μ m , from 7.0 to 9.1 μ m , and from 8.9 to 12.0 μ m are achieved at phase-matched angles of 55°, 50°, and 45°, respectively.
