Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. Apparatus for beam shaping a plurality of laser beams, the apparatus having an optical axis defining a direction of the laser beams traveling through and exiting the apparatus, the apparatus comprising: means for adjusting the angular divergence of each of the plurality of laser beams with respect to the optical axis; and means for pointing each of the plurality of laser beams so they are parallel to each other and to the optical axis, and to adjust…
