Abstract:
1. A device for generating a focused laser beam, said device comprising: a plurality of laser diodes formed into an array, each of said laser diodes for emitting a laser beamlet operated to produce a plurality of beamlets; 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.
