Abstract

Stimulated Brillouin Scattering in multimode fiber leads to the event of beam cleanup, which has attractive potential applications in improving the beam quality of multimode fiber laser with large core diameter and high peak power. We report the experimental setup and result that using Stimulated Brillouin Scattering in 105μm core diameter GI fiber to achieve beam cleanup when the 20kW peak power pulsed pump is provided, and getting a high-quality output with M2≈1.5.
