Head of division C is Prof. Dr. Thomas Elsaesser who is jointly appointed professor at the Humboldt university at Berlin. The study of ultrafast processes in condensed matter and their applications in technology represent the main research area of Division C. Fundamental research is devoted to solids, in particular semiconductors and superconductors, semiconductor nanostructures, molecules in liquids and biomolecules, making use of techniques of ultrafast spectroscopy. Novel lasers for ultrashort pulses, methods for measurements on short time scales and the characterization of optoelectronic devices are subjects of applied research in Division C.
Division C and Division A are jointly responsible for the development and operation of the femtosecond application laboratory.
