Abstract
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.
