Abstract
A method includes generating a multimode laser beam having an initial beam parameter product (bpp) and directing the multimode laser beam to an input end of a fiber so as to produce an output beam at an output of the fiber with a final bpp that is greater than the initial bpp. Another method includes measuring a base bpp associated with a multimode laser beam generated from a laser source and emitted from an output fiber output end, determining a bpp increase for the multimode laser beam, and selecting a bpp increasing optical fiber having an input end and an output end so that the multimode laser beam with the base bpp coupled to the input end has an output bpp at the output end of the bpp increasing optical fiber corresponding to the determined bpp increase.
