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.

Diode laser module and method for the production thereof

A method is disclosed for joining an electrical contact of minor thermal function to a high-power diode laser bar, comprises the step of joining the contact and the HDB by a joining material containing an adhesive. A high-power diode laser bar-contact arrangement comprises a high-power diode laser bar, an electrical contact of minor thermal function and a joint zone between the HDB and the contact. The joint zone contains a joining material with an adhesive. The disclosure also describes a high-power diode laser comprising an HDB, two electrical contacts of minor thermal function and two joint zones between the contacts and the HDB. The joint zones contain joining materials with adhesives. A high-power diode laser stack is also described.
