Abstract
A method for laser processing a workpiece is provided. The workpiece includes a material transparent to a laser beam of the laser processing. The method includes splitting an input laser beam by using a beam splitter into a plurality of partial beams. The splitting of the input laser beam is performed by application of phases to a beam cross section of the input laser beam. The method further includes focusing the plurality of partial beams decoupled from the beam splitter by using a focusing optical unit. Multiple focus elements are formed by the focusing of the plurality of partial beams. The method further includes subjecting the material of the workpiece to at least a subset of the multiple focus elements. The application of the phases is performed in such a way that at least two of the multiple focus elements have different intensities.
