Abstract

An arrangement for the guidance or conductance of a beam during the treatment of a workpiece with a laser, especially during a surface treatment by the laser beam, through the intermediary of mirrors which are interposed in the path of the beam intermediate a laser source and the workpiece. At least one deflecting mirror of the mirrors is equipped with adjusting elements for implementing a locally variable topography of its mirror surface, and is actuated from a control apparatus for effectuating a deformation or distortion of the cross-sectional geometry of the beam in conformance with the measure of a specified geometry of the beam focal point on the surface of the workpiece.
