  • Publication number: 20200136348
    Abstract: A semiconductor laser includes a contact carrier having electrical contact surfaces to electrically contact a semiconductor layer sequence, an electrical connecting line from a main side of the semiconductor layer sequence facing away from the contact carrier and a plurality of capacitors, wherein the connecting line is located on or in the semiconductor layer sequence, at least two of the capacitors are present, the capacitances of which differ by at least a factor of 50, the capacitor having a smaller capacitance is configured to supply the active zone with current immediately after a switch-on operation, and the capacitor having the larger capacitance is configured to a subsequent current supply, the capacitor having the smaller capacitance directly electrically connects to the active zone, and a resistor is arranged between the capacitor having the larger capacitance and the active zone, the resistor having a resistance of at least 100 ?.
