Abstract
The invention relates to a laser diode (2) comprising a plurality of individual emitters (EE) constructed on a substrate (8), said laser diode (2) comprising a housing which consists of a first contact part (13), a second contact part (15), an optical element (19b), a backplate (12) and two side pieces (11), with a plurality of first spacers (9o) being arranged between the substrate (8) and the first contact part (13) and a plurality of second spacers (9u) being arranged between the individual emitters (EE) and the second contact part (15). Incisions (17a) through which a cooling medium can flow are formed between each of the individual emitters (EE). The invention also relates to a device comprising at least one laser diode (2) of this type.
