Patent ID: 7444046

Claim:
A laser system comprising: a diode laser array comprised of a plurality of emitters, wherein each of said plurality of emitters emits an output beam from an output facet, and wherein each of said output beams has a fast axis of divergence and a slow axis of divergence; and a one piece coupling optic adjacent to said output facets of said plurality of emitters of said diode laser array, wherein said one piece coupling optic has a planar back surface which is substantially parallel to a front face of said diode laser array, and wherein said one piece coupling optic further comprises a plurality of optical elements corresponding to said plurality of emitters, wherein each of said plurality of optical elements has a tilted front surface, and wherein each of said plurality of optical elements is shaped to reduce said fast axis of divergence of said output beam of said corresponding emitter of said plurality of emitters; and an optical fiber array comprised of a plurality of optical fibers, wherein said plurality of optical fibers correspond to said plurality of optical elements and said plurality of emitters.
