Abstract
A semiconductor laser arrangement for high output power in the lateral fundamental mode. A semiconductor laser region is provided in which a waveguide is provided for wave guidance, this waveguide being dimensioned such that the laser emission oscillates in the fundamental mode perpendicularly to its propagation direction. The arrangement has a coupling region, and an intensification region in which the lateral wave guidance is cancelled and is provided with a contact for current injection.
