Abstract

A high-power diode laser and a method for mounting same are described. Predetermined breaking locations in the laser bar are provided which, during cooling after the laser bar has been soldered to a heat sink having a smaller thermal expansion coefficient, lead to breakage at defined locations between the single laser diodes of the laser bar. As a result of the physical division of the laser bar, it is possible to use a solder which has low ductility (hard solder) at room temperature, since destruction of the single laser diodes of the laser bar as a result of mechanical stresses can be ruled out.
