Abstract

Laser material processing requires intensities of up to 10⁹ W/cm² at power levels ranging from several watts to tens of kilowatts. Single laser diodes emit a highly divergent beam at much lower power. To make them available for material processing, radiation of many diode lasers has to be gathered and combined into one beam with reasonable beam quality. A number of different design approaches have been investigated worldwide by various research groups. In this paper, two commercially available high power diode laser systems are presented and assessed. By means of a comparison of beam characteristics, suitable applications in material processing are identified for both systems. Suggestions of possible industrial applications carried out at the Zentrum Fertigungstechnik Stuttgart are presented and discussed.
