Abstract
The invention relates to a method for producing a swaging in a workpiece, wherein a laser beam is guided through a beam guide over the surface of the workpiece in order to produce said swaging. The focal position of the laser beam is controlled in such a way that it can be varied at least temporarily in depth direction of the swaging. A device for the production of a swaging () in a workpiece () has a laser light source () for producing a laser beam for removing material, a focus adjustment device () for adjusting the focal position of the laser beam, a beam guide () for guiding the laser beam () over the surface of the workpiece and a control device () for controlling the focus adjustment device () and the beam guide (). The control device is designed to control the focal position of the laser beam by means of the focus adjustment device () at least temporarily to variable values in depth direction of the swaging.
