Paper Abstract

High power diode lasers gain considerable interest for materials processing applications, since they are very efficient, easy to use, reliable and almost service free. In contrast to conventional lasers, state-of-the-art high power diode lasers consist of a high number incoherently coupled individual semiconductor lasers, which are combined to one unit by use of semiconductor technology, micro- mechanics and micro-optics. A power range from 10 W until up to 8 kW can be covered. This paper describes the technology of diode lasers in the range between 30 and 150 W. The diode lasers have already successfully entered the industrial manufacturing area. As applications of lasers in this power range soldering and polymer welding are described in more detail.
