Abstract
In various embodiments, laser delivery systems feature one or more optical elements for receiving a radiation beam and altering the spatial power distribution thereof, a lens manipulation system for changing a position of at least one optical element within the path of the radiation beam, and a controller for controlling the lens manipulation system to achieve a target altered spatial power distribution on a workpiece.
