ABSTRACT:
Laser beam scanning system combines multiple light beams to achieve a selectable intensity, high power scanning beam. A polarizing beam splitting prism of the Thompson type is employed as a multiple input beam combiner. The input laser beam components can be made selectively coincident or closely parallel to form an output beam which is then redirected in a scanning motion and focused to an exposure plane.
