Abstract

A laser assembly (1710) for generating an assembly output beam (1712) includes a laser subassembly (1716) including a first laser module (1716A) and a second laser module (1716B), a transform assembly (1744), and a beam combiner (1746). The first laser module (1716A) emits a plurality of spaced apart first laser beams (1720A). The second laser module (1716B) emits a plurality of spaced apart second laser beams (1720B). The transform assembly (1744) is positioned in a path of the laser beams (1720A) (1720B). The transform assembly (1744) directs the laser beams (1720A) (1720B) to spatially overlap at a focal plane of the transform assembly (1744). The beam combiner (1746) is positioned at the focal plane that combines the lasers beams (1720A) (1720B) to provide a combination beam. The laser beams (1720A) (1720B) directed by the transform assembly (1744) impinge on the beam combiner (1746) at different angles.
