Patent ID: 11224939

Abstract:
An apparatus and a method for thermal processing within a processing region (1) at a workpiece surface (2) by means of a laser beam (6) emitted by at least one radiation source (5). Arranged in the beam path of the laser beam (6) between the at least one radiation source (5) and the processing region (1) on the workpiece surface (2), there is at least one element (10, 11, 12) by means of which the intensity of the laser beam (6) is modifiable in a locally defined manner within the processing region (1). As an alternative or in addition thereto, the intensity of at least one of the laser beams (6) is modifiable in a locally defined manner within the processing region (1) by a defined actuation of the plurality of radiation sources (5) such that a locally defined distribution of the intensity of the laser beam (6) striking the workpiece surface (2) is achievable within the processing region (1).
