The C60 cluster is an interesting model system for studying laser-matter interaction. The high degree of symmetry facilitates the studies of a complex system. One characteristic of great interest is the energy redistribution after the initial fs-laser pulse excitation. The mechanisms and time scales for energy redistribution are of considerable interest for understanding and controlling their dynamical behavior. Fragmentation can provide an indirect measure of the transfer of energy from the electronic to the vibrational degrees of freedom. Pump-probe measurements have been made to monitor the fragmentation of C60 on the femtosecond and picosecond time scale. This presentation will cover recent results from pump-probe measurements, as well as discuss the applications of pulse shaping to control the dynamics.
