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