摘要：An arrangement for the guidance or conductance of a beam during thetreatment of a workpiece with a laser, especially during a surface treatment by the laserbeam, through the intermediary of mirrors which are interposed in the path of the beamintermediate a laser source and the workpiece. At least one deflecting mirror of themirrors is equipped with adjusting elements for implementing a locally variabletopography 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 inconformance with the measure of a specified geometry of the beam focal point on thesurface of the workpiece.
