Imaging ultrafast molecular dynamics

In our group, a variety of different light-induced strong field processes are studied for molecules and nano-objects using ultrashort laser pulses. For such studies, a laser system with few-cycle pulses (<5 fs) and high repetition rate (10 kHz) is used. By focusing the laser, intensities up to 1015 W/cm² are reached, which is sufficient to ionize molecules multiple times. We detect the time of flight and positions for both the ions and electrons providing us with complete momentum information for each particle. Using this method, different processes are addressed, as for example: Can UV excitation alter the reactivity of molecules on ultrashort time scales? How does the presence of a nanoparticle influence the dissociation behavior of molecules? Can we control which molecular bonds break by changing fundamental properties of the laser light?

As a master student in our group, you will learn the theoretical background of ultrafast physics and experience the daily life of experimental laser optics combined with vacuum techniques. The measurements are followed by statistical data evaluation using MatLab, Python and C++. Working in a highly motivated team, you will be well supported during your thesis by PhD students and postdocs.
