Abstract: Apparatus and methods are disclosed for distributing and delivering laser radiation with substantially uniform intensity to multi-spatial locations. Laser radiation (14) is directed into a fiber optic waveguide (20) which homogenizes the spatial intensity of the laser beam via mode-mixing. The laser radiation is then coupled from the mode-mixing waveguide to multiple distribution fibers (26) that are terminated at desired spatial locations, e.g., at the distal end of a surgical tool (45). The output from each of the multiple distribution fibers is laser radiation of substantially uniform intensity.
