A laser radiation source which is scalable with respect to output is designed in such a way that laser diode elements can be arranged on a carrier so as to be stacked equidistantly and with low stress at a low manufacturing cost. The laser radiation source comprises a vertical stack of laser diode elements contacted on both sides via electrically conductive substrate layers, and at least one multi-layer carrier comprising a first and a second metallic layer which are separated by at least one electrically insulating layer of nonmetallic material. At least one of the metallic layers is divided into metallic layer regions which are arranged adjacent to one another and at a distance from one another. Oppositely polarized substrate layers of adjacent laser diode elements are arranged on common layer regions of a metallic layer. Collimating lenses serve to collimate the radiation emitted by the laser diode elements.

A diode laser component is disclosed for providing a passive cooling heatsink with improved heat spreading such that a diode laser component which uses a heatsink of this type is constructed so as to be thermally symmetrical and compact and can be used for multiple purposes, particularly as regards beam control and electrical circuitry. The heatsink, which carries a diode laser bar on a mounting surface, contains an area for heat spreading which is enclosed by material and surrounds all edges of the mounting surface. Recesses for fastening of elements are arranged in the heatsink outside of the area for heat spreading.
