Abstract: A method of producing a plurality of laser diodes includes providing a plurality of laser bars in a composite, wherein the laser bars each include a plurality of laser diode elements arranged side by side, and the laser diode elements include a common substrate and a semiconductor layer sequence arranged on the substrate, and a division of the composite at a longitudinal separation plane extending between two adjacent laser bars leads to formation of laser facets of the laser diodes to be produced, and structuring the composite at at least one longitudinal separation plane, wherein a structured region is produced in the substrate.
