Semiconductor laser with reduced heat loss

摘要

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 ).
