Institut für Strahlwerkzeuge

The Institut für Strahlwerkzeuge (IFSW) of the University of Stuttgart, founded in 1986, is reputed as one of the leading laser research centres worldwide. Its strength is based on a holistic research approach covering every aspect from laser sources to their applications and ranging from fundamental investigations to industrial technology transfer. The main activities at the IFSW are currently concerned with selected topics in the fields of laser beam sources (especially the thin-disk laser), optical elements and components for beam delivery and beam shaping as well as fundamental investigations on the light-matter interaction with the subsequent process development of macro and micro applications for industrial manufacturing.

Comparison of heat conduction mode and deep penetration mode by means of high-speed synchrotron X-ray videos during laser beam welding Aug 4, 2021 Hagenlocher, Christian; Lind, Jannik; Wagner, Jonas; Hummel, Marc; Olowinsky, Alexander; Weber, Rudolf; Graf, Thomas, 2021, "Comparison of heat conduction mode and deep penetration mode by means of high-speed synchrotron X-ray videos during laser beam welding", https://doi.org/10.18419/darus-2078, DaRUS, V1 There are two modes of laser beam welding: the heat conduction mode and the full penetration mode. The heat conduction mode is present if the intensity of the laser beam is to low to evaporate but sufficient to melt the irradiated material. This welding mode results in a very sta...
High-speed synchrotron X-ray video of the laser beam cutting process in a 2 mm thick sheet of aluminium Jun 15, 2021 Lind, Jannik; Hagenlocher, Christian; Blazquez-Sanchez, David; Hummel, Marc; Olowinsky, Alexander; Weber, Rudolf; Graf, Thomas, 2021, "High-speed synchrotron X-ray video of the laser beam cutting process in a 2 mm thick sheet of aluminium", https://doi.org/10.18419/darus-1824, DaRUS, V1 The generation of low surface roughness of the cut edge during laser beam cutting is a challenge. The striation pattern, which determines the surface roughness, can be distinguished into regular and interrupted striations, the latter resulting in an increased surface roughness. I...
