Abstract
A method and apparatus for laser beam splitting and shaping is disclosed wherein two beam splitters are used to split one input laser beam into four beams in a generally rectangular pattern. Half-wave plates are used to adjust the power of the input laser beam between the four laser beams. A variable power optical telescope comprising negative and positive lens pairs for the four laser beams is used to adjust the divergence of the four beams, and pointing control prism wedges are used to point or steer the four beams to be parallel to each other and to adjust their relative spacing to create a flat top profile.
