Abstract

A method for processing moving workpieces with laser radiation that is focused on a to-be-processed workpiece surface by means of a laser beam that is moved but not relative to the workpiece. The laser beam is focused in a line-like manner and its beam spot corresponds practically exclusively and with full a real coverage to the work piece surface to be processed.
