Abstract
The beam-cleanup properties of stimulated Raman scattering in a long multi-mode fiber and its application to laser brightness enhancement have been investigated. We show that in a multi-mode fiber that supports propagation of a highly aberrated pump beam with the beam quality (M2) as high as 20, a clean Gaussian-like Stokes beam is generated. The dramatic enhancement in beam quality achieved in the present investigation clearly demonstrates the utility of fiber-based Raman beam cleanup devices for laser brightness enhancement.
