Abstract

The present invention relates to a device for generating laser radiation.An object of the present invention is to indicate a laser diode which simultaneously has a high degree of efficiency and a low degree of far field divergence.The diode laser according to the invention comprises a current barrier (5), characterized in that the current barrier (5) extends along a third axis (X), wherein the current barrier (5) has at least one opening, and a first width (W1) of the opening of the current barrier (5) along the third axis (X) is smaller than a second width (W2) of the metal p-contact (8) along the third axis (X).
