Abstract (en)
[origin: WO2020109209A1] The present invention relates to a device and a method for beam shaping and beam movement during laser material processing with a laser beam source (1) for continuously emitting a laser beam (2), a first optical deflection element (3), a second optical deflection element (4), and an optical focusing element (5) arranged between the second optical deflection element (4) and a workpiece surface (7) to be processed. The second optical deflection element (4) is configured to displace a point of incidence of the laser beam (2) on the workpiece surface (7), and the first optical deflection element (3) is configured to alter a position of a focal plane of the laser beam (2) relative to the workpiece surface (7) by means of a translational movement and/or to change an intensity distribution within a beam cross section of the laser beam.
