Abstract:
1. A laser radiation source comprising: a vertical stack of laser diode elements which are contacted on both sides via substrate layers of electrically conducting material; and at least a first multi-layer carrier including a first and at least a second metallic layer which are separated by at least one electrically insulating layer of nonmetallic material; wherein 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; wherein oppositely polarized substrate layers of adjacent laser diode elements are arranged on common layer regions of a metallic layer; and wherein the sum of the thicknesses of the first and second metallic layers to the sum of the thicknesses of the at least one electrically insulating layer has a ratio of from 1.5:1 to 2.0:1.
