    Authors:
    Eckhard Beyer, Fraunhofer IWS; Dresden University of Technology; Dresden Germany
    Presented at PICALO 2008

    In materials processing with high power lasers the diode laser has established itself for processes without need of extreme intensities. The presentation demonstrates actual applications in the field of hardening, brazing and coating with diode lasers. For cutting and 2D-welding processes CO2 lasers are applied, whereas the Nd:YAG laser is the well proven laser for 3D-welding. These statements are affirmed with current examples. Nevertheless, this state-of-the-art will be faced considerable changes in the near futu...
