Abstract

A diode laser having a beam-forming device and a method for producing it are described. The diode laser includes at least one diode laser bar, the diode laser bar having a multitude of emitters, the emitters being disposed next to each other in the direction of their longitudinal axes. The diode laser includes a beam-forming device assigned to the diode laser bar, for the laser beam emerging from the diode laser bar, the beam-forming device having a light-guide device having a plurality of fibers, into which the laser beam is coupled. The maximum thickness of the optical fibers at their end facing the diode laser bar is considerably smaller than their width.
