Welcome

How do the building blocks of matter move after irradiation with very short and intense laser pulses and can this movement be controlled and made use of?

To do this, we illuminate the matter with extremely short laser pulses in the quadrillionth part of a second and watch the ultrafast dynamics with stroboscopic methods in slow motion (femtosecond spectroscopy). Using optical synthesizers, we shape the laser light in time and can thus control the ultrafast dynamics (ultra-fast laser control) by customizing the energy transfer.

The span of our investigation ranges from free electrons, atoms and molecules in the gas phase to dye molecules and colloidal quantum dots in solution, as well as excitation and removal (ablation) mechanisms in solids and organic tissue.
