Femtosecond spectroscopy and ultrafast laser control
In the femtosecond spectroscopy and ultrafast laser control laboratories, research is being carried out into the use of ultrashort laser pulses, which can be used to process materials and identify molecules, for example.
How do the building blocks of matter move after irradiation with very short and intense laser pulses and can this movement even be specifically controlled and thus made usable?
In its laboratories, the Experimental Physics research group is looking for answers to these questions by illuminating matter with extremely short laser flashes (one femtosecond corresponds to one quadrillionth of a second) and observing the ultra-fast dynamics in slow motion using stroboscopic methods (femtosecond spectroscopy). The laser light can be shaped in time with the aid of optical synthesizers in order to adapt the energy supply to the ultrafast dynamics (ultrafast laser control).
In the laboratory, for example, free electrons, atoms and molecules in the gas phase, but also excitation and ablation mechanisms in solids and in biological tissue are investigated.
Application relevance of research
e.g. generation of micro- and nanostructured surfaces, material testing, cancer detection
