Abstract

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.
