Abstract:
The interaction of few-cycle laser pulses with matter has attracted
considerable interest as increasingly shorter pulses became available. A
theoretical study of atomic single ionization driven by a linearly
polarized short laser pulse within the single electron approximation will 
be presented. A simple semiclassical analysis of the interference pattern 
in the angular distribution can be performed in the tunneling regime: The 
electron released with low momentum experiences interference processes 
displaying a near-threshold axial shape structure. A simple universal 
classical formula that predicts the dominant angular momentum for 
tunnel-ionized slow electrons propagating in the combined Coulomb and 
laser fields is found. I will also show recent investigations on the 
effect of the Coulomb potential of the atomic core on the dynamics of the 
detached electron.
