Abstract
A light beam with non-uniform cross-sectional intensity profile is positioned into a central portion and two side lobes and the two side lobes are folded over the central portion to form a concentrated beam at a focus plane having substantially uniform intensity profile. The partitioning and folding may be done by mirror pairs disposed along the axis of the beam, or a trapezoidal prism.
