This business area encompasses the development of diode laser modules and systems as well as diode-pumped solid-state lasers, the design of new diode laser structures, the microassembly of diode lasers and optical components, and the development of plasma systems. Outstanding project results, which have been successfully transferred to practical applications in close cooperation with industrial partners, include the transversally diode-pumped 5 kW solid-state laser and diode laser modules for joining plastic components. In cooperation with the Fraunhofer IAF new structures are being designed which permit the manufacture of diode lasers demonstrating higher beam quality. The business area continues to enjoy a unique reputation in the assembly of high-power diode lasers and in particular the installation of partially automated assembly facilities. Work in the plasma technology sphere focuses on the development of EUV beam sources for semiconductor lithography. The main target markets for the business area as a whole are laser machining, medical engineering and metrology, along with the component market for information and communications technology.
