The invention relates to a device and a method for thermal machining in a machining region (1) on a workpiece surface (2) by means of a laser beam (6) emitted by at least one radiation source (5). At least one element (10, 11, 12) is arranged in the beam path of the laser beam (6), between the at least one radiation source (5) and the machining region (1) on the workpiece surface (2), said element being used to modify the intensity of the laser beam (6) in the machining region (1) in a locally defined manner. Alternatively or additionally, the intensity of at least one of the laser beams (6) in the machining region (1) can be modified in a locally defined manner, by means of a defined control of a plurality of radiation sources (5), such that a locally defined distribution of the intensity of the laser beam (6) hitting the workpiece surface (2) can be obtained in the machining region (1).
