Abstract: The invention relates to a laser diode (10) which has at least one active layer (12) which is arranged within a resonator (14) and is operatively connected to a outcoupling element (16), and further at least one contact layer (18) for coupling charge carriers into the active layer (12), wherein the resonator (14) comprises at least a first section (20) and a second section (22), wherein the second section (22) comprises a plurality of separate resistor elements (24) having a specific electrical resistivity greater than the specific electrical resistivity of the regions (26) between adjacent resistor elements (24), wherein a width (W3) of the resistor elements (24) along a longitudinal axis (X1) of the active layer (12) is less than 20 μm, and a projection of the resistor elements (24) on the active layer (12) along the first axis (Z1) overlap with at least 10% of the active layer (12).
