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