Laser assembly with beam combining

A laser assembly that generates an assembly output beam, the laser assembly comprising:

• a laser subassembly including a first laser module that emits a plurality of spaced apart, parallel, first laser beams, and a second laser module that emits a plurality of spaced apart, parallel second laser beams;
• and wherein the first laser beams and the second laser beams are parallel to each other;
• a beam adjuster positioned in a path of the parallel first and second laser beams, the beam adjuster adjusting the spacing between the plurality of laser beams;
• and wherein the laser beams exiting the beam adjuster are parallel to each other;
• a transform assembly positioned in a path of the parallel laser beams that exit the beam adjuster, the transform assembly directing the laser beams to spatially overlap at a focal plane of the transform assembly;
• and
• a beam combiner positioned at the focal plane that combines the lasers beams to provide a combination beam.

A method for generating an assembly output beam comprising:

• emitting a plurality of spaced apart first laser beams with a first laser module;
• emitting a plurality of spaced apart second laser beams with a second laser module;
• wherein the first laser beams and the second laser beams are parallel to each other;
• adjusting the spacing between the parallel laser beams with a beam adjuster positioned in the path of the parallel laser beams;
• wherein the laser beams exiting the beam adjuster are parallel to each other;
• directing the laser beams to spatially overlap at a focal plane with a transform assembly positioned in a path of the laser beams that exit the beam adjuster;
• and
• combining the lasers beams with a beam combiner positioned at the focal plane;
• wherein the laser beams directed by the transform assembly impinge on the beam combiner at different angles, and wherein the laser beams exiting from the beam combiner are substantially coaxial.
