Strong-field ionization of atoms can be investigated on the attosecond time scale by using the attoclock method, i.e. by observing the peak of the photoelectron momentum distribution (PMD) after applying a laser pulse with ...

High-intensity femtosecond laser pulses in the visible or infrared range can induce electron emission. This single-ionization process may be interpreted as a sequence of (nonadiabatic) tunnel ionization and subsequent ...

In strong-field ionization processes, two-color laser fields are frequently used for controlling subcycle electron dynamics via the relative phase of the laser fields. Here we apply this technique to velocity map imaging ...
