Abstract We review the semiclassical two-step model for strong-field ionization. The semiclassical two-step model describes quantum interference and accounts for the ionic potential beyond the semiclassical perturbation theory. We discuss formulation and implementation of this model, its further developments, as well as some of the applications. The reviewed applications of the model include strong-field holography with photoelectrons, multielectron polarization effects in ionization by an intense laser pulse, and strong-field ionization of the hydrogen molecule.

Using the generalized Keldysh theory, we investigate the quantum interference and the laser pulse phase effects by tunneling photoionization of an excited hydrogen atom. We assume that its initial state be a linear combination of 1s, 2s, 2p Stark-shifted atomic states. It is found that within the Keldysh approximation, quantum interference can take place among the 1s, 2s, and 2pz states, while this is not the case among 1s, 2s, 2pz and 2px, 2py, or 2px and 2py themselves. From the numerical calculations, we predict that the prominent destructive quantum interference takes place between 2s and 2pz atomic orbitals. In addition, we have found that in general, the laser pulse phase does not affect the individual photoionization rates while it does affect the quantum interference terms.

And Control

Controlling chemical reactions by light, i.e., the selective making and breaking of chemical bonds in a desired way with strong-field lasers, is a long-held dream in science. An essential step toward achieving this goal is to understand the interactions of atomic and molecular systems with intense laser light. The main focus of experiments that were performed thus far was on quantum-state population changes. Phase-shaped laser pulses were used to control the population of final states, also, by making use of quantum interference of different pathways. However, the quantum-mechanical phase of these final states, governing the system’s response and thus the subsequent temporal evolution and dynamics of the system, was not systematically analyzed. Here, we demonstrate a generalized phase-control concept for complex systems in the liquid phase. In this scheme, the intensity of a control laser pulse acts as a control knob to manipulate the quantum-mechanical phase evolution of excited states. This control manifests itself in the phase of the molecule’s dipole response accessible via its absorption spectrum. As reported here, the shape of a broad molecular absorption band is significantly modified for laser pulse intensities ranging from the weak perturbative to the strong-field regime. This generalized phase-control concept provides a powerful tool to interpret and understand the strong-field dynamics and control of large molecules in external pulsed laser fields.
