Individually addressed high-power diode-laser-bars for material processing

Abstract

In order to widen the applications of high-power diode-laser-bars in the fields of micro-system technology and printing industry (e.g. soldering electronic components or rapid-prototyping) the intensity profile must be adjusted to the work piece's respective geometry. In this presentation an estimation of the thermal and electrical crosstalk for different geometries of high-power diode-laser-bars is discussed. Different methods to increase the fill factor are shown. At the conclusion three prototypes with 19 up to 48 individually addressable high-power diode-laser-bars used in the field of micro-system technology and printing industry are presented.
