Classification: CPC G  B | IPC B  G

Claim 0:
1. A laser delivery system for receiving and altering a spatial power distribution of a radiation beam from a beam source and focusing the radiation with the altered spatial power distribution onto a workpiece, the system comprising:
a triplet collimator for increasing a divergence of the radiation beam;
disposed optically downstream of the triplet collimator, a focusing lens for receiving the radiation beam and focusing the beam toward the workpiece;
disposed optically upstream of the focusing lens, at least one optical element for receiving the radiation beam and altering the spatial power distribution thereof;
a lens manipulation system for changing a position of the at least one optical element within a path of the radiation beam; and
a controller for controlling the lens manipulation system to achieve a target altered spatial power distribution on the workpiece,
wherein the triplet collimator comprises (i) a first plano-concave lens, (ii) a second meniscus lens, and (iii) a third plano-convex lens.
