Abstract
A semiconductor laser having a semiconductor chip (1) which contains an active layer (5) and emits radiation in a main radiating direction (6). The active layer (5) is structured in a direction perpendicular to the main radiating direction (6) in order to reduce heating of the semiconductor chip (1) by spontaneously emitted radiation (10).
