Claim 37:
38. 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, the at least one optical element comprising a first optical element and a second optical element;
a lens manipulation system configured to change at least one of (i) a position of the first optical element within a path of the radiation beam, (ii) a position of the second optical element within the path of the radiation beam, or (iii) a distance between the first and second optical elements; and
a controller for controlling the lens manipulation system to achieve a target altered spatial power distribution on the workpiece.
