Abstract

The invention relates to a process for material treatment with diode radiation, especially laser diode radiation. To match the radiation profile to the treatment process, the process is so carried out that radiation emitted from a multiplicity of diodes is directed with a predetermined radiation profile upon the treated region of the workpiece and that a change in the intensity distribution in the radiation profile is effected by controlling the diode output power.
