1. An addressable array laser processing system, the addressable array laser processing system comprising: at least three laser systems, wherein each laser system comprises:
a. at least three laser diode assemblies;
b. each of the at least laser diode assemblies comprises at least ten laser diodes, wherein each of the at least ten laser diodes is capable of producing a blue laser beam, having a power of at least about 2 Watts and a beam parameter product of less than 8 mm-mrad, along a laser beam path, wherein each laser beam path is essentially parallel, whereby a space is defined between the laser beams traveling along the laser beam paths; and
c. a means for spatially combining and preserving brightness of the blue laser beams positioned on all of the at least thirty laser beam paths, the means for spatially combining and preserving brightness comprising a collimating optic for a first axis of a laser beam, a vertical prism array for a second axis of the laser beam, and a telescope; whereby the means for spatially combining and preserving fills in the space between the laser beams with laser energy, thereby providing a combined laser beam a power of at least about 250 Watts, and a beam parameter product of less than 40 mm-mrad;
each of the at least three laser systems configured to couple each of their combined laser beams into a single optical fiber; whereby each of the at least the three combined laser beams being capable of being transmitted along its coupled optical fiber; the at least three optical fibers in optical association with a laser head; and a control system; wherein the control system comprises a program having a predetermined sequence for delivering each of the combined laser beams at a predetermined position on a target material.
