Abstract:


We monitor the intensity dependence of photoionization of argon at 800 nm at pulse durations of 100 fs employing momentum-resolved photoelectron imaging spectroscopy. We compare our data with numerical solutions of the time-dependent SchrC6dinger equation (TDSE) using a model potential for argon and the single active electron approximation (SAE). We find quantitative agreement in all dominant features in energy and angle. The energy and angular distributions of the photoelectrons allow us to identify selective dominant ionization channels.
