In high-power micro-modules, several semiconductor lasers are combined on a compact footprint using wavelength division multiplexing and/or polarization coupling. As a result, high optical output powers can be achieved. The emission is available as a free-space beam or from an optical fiber . The modules can therefore be used both as pump sources for solid-state lasers and in direct material processing. In addition to the optical concept, the thermal design is decisive.
