Abstract
A diode bar and a method for producing a laser diode bar are disclosed. In an embodiment a laser diode bar includes a plurality of emitters arranged side by side, the each emitter having a semiconductor layer sequence with an active layer suitable for generating laser radiation, a p-contact and an n-contact, wherein the emitters comprise a group of electrically contacted first emitters and a group of non-electrically contacted second emitters, wherein the p-contacts of the first emitters are electrically contacted by a p-connecting layer, and wherein the p-contacts of the second emitters are separated from the p-connecting layer by an electrically insulating layer and are not electrically contacted.
