Research at the Institut für Strahlwerkzeuge (IFSW)

Laser Development and Optics

The aim of the research is the constant further development of reliable and powerful laser systems with specifically optimized properties for different fields of application and the required laser optics.

Current efforts concentrate on the reliable generation of radiation with high beam quality and the power scalability of lasers in all modes of operation (cw, Q-switched, mode locked).

At the IFSW, the cradle of the thin-disk laser, research into the further development of this robust laser concept draws on decades of scientific and technical expertise.

The development of measurement methods for the qualification of optical elements especially under thermal load is also carried out within the framework of this research area. The technical expertise gathered with these investigations leads to a continuous improvement and further developments of laser sources, beam control and beam delivery systems for diffraction-limited high-power laser radiation.

Since several years the IFSW is also intensely engaged in the investigations on novel fiber concepts and the development of fiber lasers.

Strongly related to the research on high-power lasers we also develop special and novel optical elements. In particular these are diffractive and active optical elements as well as fiber integrated optical components. With the fiber manufacturing facility - consisting of an MCVD perform lathe and a drawing tower - recently installed in the building of the IFSW the research and development on the production methods for high-power capable fibers and the investigations on particular fiber lasers also constitute an important element in our holistic research activities.
