    摘要: 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.

    摘要: 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).

    摘要: 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).

    摘要: A light source assembly includes a housing assembly, a plurality of disparate light sources that are coupled to the housing assembly, a power source, a control system and a selector assembly. Each of the light sources generates an output beam that is directed away from the housing assembly, wherein each of the output beams has a center wavelength that is in a different wavelength range than each of the other output beams. The power source provides electrical power to each of the light sources. The control system selectively controls the electrical power that is provided by the power source to the light sources. The selector assembly is electrically connected to the control system, and is selectively controllable to selectively direct current to each of the light sources to generate the desired output beams.
