Paper Abstract

High power diode lasers form a few Watts up to several Kilowatts have entered industrial manufacturing environment for materials processing applications. The technology has proven to show unique features, e.g. high efficiency, small size, low energy consumption and high reliability. This paper provides a description of high power diode laser technology and applications and evaluates the benefits and restrictions of this laser technology. As an outlook an ambitious research project, the five year National German 'MDS'-project is shortly described. New developments in the opto-semiconductor technology itself, but also in micro- optics and precision mounting technology will help to increase the beam quality by about one order of magnitude, so that the beam quality of today's lamp pumped high power Nd:YAG lasers can be reached. New type of laser applications are supported by the modular concept of the diode lasers.
