  Laboratory Fraunhofer ILT Laboratory

Innovative developments require extensive expertise. In the field of laser technology, the interaction between laser development and laser applications is of outstanding importance. New lasers allow new applications and new applications set the stage for new laser systems. Therefore, the Chair for Laser Technology constantly extends in cooperation with the Fraunhofer Institute for Laser Technology ILT and with leading laser manufacturers and innovative laser consumers its core competencies. The basis for the core competences are highly qualified engineers and scientists from various disciplines.

Technical Infrastructure
The technical infrastructure of the Chair includes a mechanical and electronic workshop, a metallurgy laboratory, a photo laboratory, a laboratory for optical measurements as well as a design department.

Scientific Infrastructure
The scientific infrastructure includes e.g. a literature library, literature and patent databases and scientific oriented software and databases for process documentation.
