computational photonics

Our research is mainly focused on the interaction of high-intense ultrashort laser-pulses with matter. In particular the understanding of the dynamics of such interaction is very important for potential applications.

Pulse compression in pressurized cells filled with noble gases by femtosecond filaments is one of these applications. The impressively simple setup and the high compression rates achieved so far attracts much interest at recent international conferences. Fully space-time resolved simulations can give insight into the details of the compression mechanisms which are not accessible in experiments (see figure).
Another hot topic is the possibility of using high power lasers to generate multi-MeV proton beams. Such beams can be used to initiate thermonuclear reactions in the so-called fast ignitor scheme for ICF. Due to their good laminarity, collimation and short duration, they are also used for time resolved radiography in plasma experiments. Potential medical applications are hadron therapy and isotope creation.
In our research group we try to gain deeper understanding of such processes by means of numerical simulations. Recent development in computer technology makes is possible to recreate whole physical experiments inside a massivly parallel compute cluster. In doing so, we can get insight into processes which are not accessible in experiments.
