Abstract
In one embodiment, the semiconductor laser () comprises a semiconductor layer sequence () based on the material system AlInGaN with at least one active zone () for generating laser radiation. A heat sink () is thermally connected to the semiconductor layer sequence () and has a thermal resistance towards the semiconductor layer sequence (). The semiconductor layer sequence () is divided into a plurality of emitter strips () and each emitter strip () has a width (b) of at most 0.3 mm in the direction perpendicular to a beam direction (R). The emitter strips () are arranged with a filling factor (FF) of less than or equal to 0.4. The filling factor (FF) is set such that laser radiation having a maximum optical output power (P) can be generated during operation.
