Abstract

In a diode laser module and a method for the production thereof, there is a need to fix the optical elements required for collimating, beam shaping and/or beam rearrangement of the radiation of a laser diode element with high reproducibility and long-term stability in an optically aligned manner, wherein the optically aligned state is produced by a successive adjustment of the optical elements in the beam of the switched-on laser diode element. It must be ensured that the fixing can be carried out in a process that is at least partially automated. At least one intermediate carrier is arranged on a heat-dissipating carrier serving to cool the laser diode element. The heat conductivity of the intermediate carrier is less than that of the heat-dissipating carrier, and the alignment of the optical components and fixation by sequential soldering is carried out on the surface of the intermediate carrier.
