Ultrafast Science


(c) Juniks

The scientific scope of Ultrafast Science research unit (D4 - Prof. D. Turchinovich, Prof. W. Pfeiffer) is the studies of dynamics of electrons, lattice, and spins in condensed matter on the ultrafast timescales ranging from attoseconds (10-18 s) to picoseconds (10-12 s). Advanced experimental techniques used in our research unit range from attosecond XUV spectroscopy to femtosecond nano-optics to terahertz spectroscopy, implemented in many different modalities. All our research methods rely on highly-elaborate femtosecond laser infrastructure, established within the research unit.
