    Abstract: A laser assembly (1210) for generating an assembly output beam (1212) includes a laser subassembly (1216) that emits a plurality of spaced apart first laser beams (1220A), a plurality of spaced apart second laser beams (1220B), a transform lens assembly (1244), a wavelength selective beam combiner (1246), and a path length adjuster (1299). The transform lens assembly (1244) collimates and directs the laser beams (1220A) (1220B) to spatially overlap at a focal plane of the transform lens assembly (1244). The path length adjuster (1299) is positioned in a path of the first laser beams (1220A), the path length adjuster (1299) being adjustable to adjust of a path length the first laser beams (1220A) relative to the second laser beams (1220B).

    Abstract: A laser assembly (10) for generating an assembly output beam (12) includes a laser subassembly (16) that emits a plurality of spaced apart laser beams (20), a beam adjuster (42), a transform lens (44A), a beam combiner (46), and an output coupler (48). The beam adjuster (42) adjusts the spacing between the plurality of laser beams (20). The transform lens (44A) focuses the laser beams (20) at a focal plane (54) and the beam combiner (46) is positioned at the focal plane (54). The beam combiner (46) combines the lasers beams (20) to provide a combination beam (58). Further, the output coupler (48) redirects at least a portion of the combination beam (58) back to the beam combiner (46) as a redirected beam (60), and transmits a portion of the combination beam (58) as the assembly output beam (12).
