ABSTRACT:
The present invention relates to an arrangement of semiconductor diode lasers stacked on top of one another, which is arranged on a substrate (1). A first diode laser (12) is arranged on the substrate (1), and a second diode laser (13) is arranged on the first diode laser (12). Between the first diode laser (12) and the second diode laser (13) there is a contact layer (6). The contact layer (6) comprises a first conductive layer (18) of a first conduction type and a second conductive layer (20) of a second conduction type and an interlayer (19) which is arranged between the first and second conductive layers (18, 20).
