1. 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 first laser beams, and a second laser module that emits a plurality of spaced apart second laser beams; wherein the first laser module is spaced apart from the second laser module; and wherein the first laser beams and the second laser beams are parallel to each other;
a beam adjuster positioned in the path of the parallel laser beams, wherein the beam adjuster adjusts 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 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; 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.
