Abstract

A processing optical unit for workpiece processing includes a birefringent polarizer configured to split at least one input laser beam into a pair of partial beams polarized perpendicularly to one another. The processing optical unit further includes a focusing optical unit arranged downstream of the birefringent polarizer in the beam path and configured to focus the pair of partial beams onto focus zones in a focal plane. The processing optical unit is configured to produce at least partly overlapping focus zones of the pair of partial beams.
