Patent ID: 8439523

Claim:
A device for generating a focused laser beam, said device comprising: a main laser array including a plurality of emitting diodes formed into an array, each of said laser diodes operating in a particular spectrum for emitting a laser beamlet operated in conjunction to produce a plurality of beamlets; at least one seed laser including an extended cavity emitting diode operating in the same particular spectrum as the diodes of the main array; a first concave reflecting mirror for converging said beamlets to a focal point; an integrating convex mirror placed at or near said focal point, said integrated convex mirror adapted for reflecting a first portion of said beamlets back toward said first reflecting mirror and for allowing a second portion of said beamlets through said integrating convex mirror; and a light transmitter adapted for transmitting said second portion of said beamlets from said integrating convex mirror, wherein said second portion of beamlets exit said light transmitter as a homogenized uniform laser beam having substantially uniform convergence and focus.
