Abstract
We report a tunable stimulated-Brillouin-scattering resonator that does not require a starting mirror or a wavelength selector. The resonator is based on the Bragg scattering from the dynamic grating within the active medium itself. The laser dye (Rhodamine 6G dissolved in ethanol) was utilized as t he active medium and was pumped by a frequency-doubled Nd:YAG laser. The qu ality factor (M-2) Of the output beam was 2.2. A single short pulse (<1 ns) with a pumping efficiency of similar to 4% was observed. (C) 2000 Optical Society of America OCIS codes: 190.5040, 190.5890, 140.2050, 140.3490, 290. 5900.
