Abstract
A method for cutting workpieces of different thicknesses includes providing at least one unprocessed laser beam, selectively forming a processing laser beam from the at least one unprocessed laser beam in accordance with a thickness of the workpiece, and cutting the workpiece with the processing laser beam. Forming the processing laser beam includes selectively coupling one or more unprocessed laser beams into one or more of a plurality of parallel, non-concentric fibers of a compound fiber, the plurality of fibers of the compound fiber having different cross-sectional shapes. A laser beam characteristic of the processing laser beam exiting the compound fiber differs depending upon which fibers of the compound fiber receive the at least one unprocessed laser beam, the laser beam characteristic of the processing laser beam differing depending on the thickness.
