Given the complexity of systems which are of interest in current applications, the simulation of femtosecond signals is a major challenge for theory. We have developed general theories for the simulation of ensemble as well as single molecule spectroscopy beyond the weakfield limit. The polarization obtained by this theory reduces to the nonlinear response function
formalism in the limit of weak field-matter interaction. For intermediate and strong pulse strengths, this theory takes into account all relevant higher-order contributions beyond the weak-field limit. We have applied our theory to simulate ensemble as well as single molecule spectroscopy of various light harvesting systems, revealing intricate energy transfer processes in these systems.
