A device and a method for beam shaping and beam movement during laser material processing with a laser beam source () for continuously emitting a laser beam (), a first optical deflection element (), a second optical deflection element (), and an optical focusing element () arranged between the second optical deflection element () and a workpiece surface () to be processed. The second optical deflection element () is configured to displace a point of incidence of the laser beam () on the workpiece surface (), and the first optical deflection element () is configured to alter a position of a focal plane of the laser beam () relative to the workpiece surface () by means of a translational movement and/or to change an intensity distribution within a beam cross section of the laser beam.
