A review is presented of the rescattering plateau in laser-induced above-threshold ionization and its various features as they were discovered over time. Several theoretical explanations are discussed, from simple momentum conservation to the quantum-mechanical improved strongfield approximation and the inherent quantum orbits or, alternatively, entirely classical methods. Applications of the plateau to the extraction of atomic or molecular potentials and to the characterization of the driving laser pulse are also surveyed.

“…Soon, better laser systems and higher accuracy in experiments showed the expected sequence of peaks in the continuum [7,8] which form well-known plateau structures. The quasistatic or two-step model [9,10,11] explains the underlying dynamics. First, the electron is ejected into a continuum state via tunneling or MP processes with nearly no kinetic energy, being subsequently accelerated by the electrical field of the laser.…”

We present angular distributions of photoelectrons of atomic model systems excited by intense linearly polarized laser pulses in the VUV-and XUV-regime. We solve the multi-dimensional timedependent Schrödinger equation for one particle on large spatial grids and investigate the direction dependence of the ionized electrons for isotropic s-states as well as p-states. Although the ponderomotive potential is small compared to the binding energy of the initially bound electron and the photon energy of the exciting laser field, richly structured photoelectron angular distributions are found which sensitively depend on the laser frequency and intensity as well as on the number of absorbed photons. The occuring shapes are explained in terms of scattering mechanisms.

“…If the intensity of the light becomes very high, multiphoton transitions can become important, ultimately reaching the situation that the electric field of the light suppresses the binding Coulomb forces as happens, e.g., in above-threshold ionization [1,2] or in the interaction of Rydberg atoms with strong half-cycle electric field pulses [3][4][5][6]. In another class of light-matter interactions, for example, in stimulated Raman adiabatic passage, the coherent properties of light are employed [7].…”

Transitions Driven by a Missing Frequency

We demonstrate an intricate combination of strong and weak interactions of a broadband half-cycle pulse with Rydberg atoms. A transition, which is resonant with a frequency that was taken out of the frequency spectrum, can be enhanced. In the experiment, the broadband ultrashort terahertz half-cycle pulse propagates through water vapor, which absorbs on discrete lines in the spectrum, thus removing frequencies from the spectrum. The resulting pulse interacts with a rubidium Rydberg atom, which has a resonant transition with one of the missing frequencies. Under certain conditions, the transition probability is enhanced although the associated frequency was missing in the spectrum.
