We investigate resonant strong field ionization of atomic hydrogen with respect to the 1s–2p transition. By 'strong' we understand that Rabi periods are executed on a femtosecond time scale. Ionization and AC Stark shifts modify the bound state dynamics severely, leading to nonperturbative signatures in the photoelectron spectra. We introduce an analytical model, capable of predicting qualitative features in the photoelectron spectra such as the positions of the Autler–Townes peaks for modest…

Above-threshold ionization of atoms by resonant XUV laser pulses
Above-threshold ionization of atoms by XUV short laser pulses with frequencies close to the resonant 1s?2p transition is investigated. We present a theory based on a variational expression using

Manipulating dynamical Rabi-splitting with two-color laser pulses.
The employed OTC scheme is shown to be efficient for controlling the dynamic Rabi-splitting through the control of quantum-path interferences involved in one-photon and two- photon absorption processes.
Quantum control and characterization of ultrafast ionization with orthogonal two-color laser pulses
It is shown that with the use of the OTC scheme, one can tailor the properties of the control pulse to lead to enhancement of the ionization rate through the Autler-Townes effect without affecting the dynamic interference, which is shown to result from constructive interferences between partial photoelectron waves having opposite-parity.
Angular shift of Autler–Townes doublet from multi-photon ionization of molecules by circularly polarized laser pulses
We theoretically study the Autler–Townes (AT) splitting of a molecule in a circularly polarized laser pulse by solving the time-dependent Schrödinger equation. We find that the AT doublet in the

Ionization of hydrogen by ion impact in the presence of a laser field resonant to bound–bound atomic transitions
We study the impact ionization of atomic hydrogen in collisions with fast ions assisted by the pulse of a weak laser field with a sub-nanosecond duration (T ~ 10−10 s). The field is linearly

A theoretical procedure is presented for the evaluation of resonant multiphoton ionisation rates for atoms interacting with intense monochromatic lasers. The essence of the procedure is to treat

We discuss the sub-cycle dynamics of strong-field ionization by an intense few-cycle laser pulse. Even at high intensities when all the excited states are embedded into the continuum, the dynamics
