Abstract

This thesis focuses on the dynamical changes in the absorption of liquid-phase targets due to the interaction with strong, ultrashort laser pulses. Therefore, it is shown that the absorption spectrum of aluminum chloride phthalocyanine (AlClPc) in the liquid phase can be dynamically modified through the time- resolved interaction with a second laser pulse, which can be explained by laser- induced coherent coupling dynamics between the ground state and an ensemble of excited states, as reproduced by a few-level toy model. Furthermore, it is shown which time-dependent effects upon the measured absorption spectra are generated due to the presence of the solvent and the non-trivial pulse-form itself, which is confirmed through a second simulation. The presented results contribute to a better understanding in how intense laser fields interact with complex molecules in solution and can, in the future, be used to improve dynamic laser-control of complex systems.
