Abstract

High-order above-threshold ionization (ATI) is investigated in the frequency domain, based on a nonperturbative quantum electrodynamics theoretical approach. The transition matrix element of high-order ATI is expressed as a superposition of products of generalized Bessel functions, which represent probability amplitudes of finding electrons with given energies. From the frequency-domain viewpoint the high-order ATI can be described simply as an ATI followed by laser-assisted collision (LAC), and the features of high-order ATI reflect mainly the characteristics of LAC. We investigate thoroughly the LAC, finding that the plateau can be simulated by a simple classical model. We also discuss the correspondence between the time- and frequency-domain pictures of rescattering ATI.

Frequency-domain interpretation of the plateaus in laser-assisted recombination and high-order harmonic generation

Journal Article Cheng, Taiwang; Li, Xiaofeng; Ao, Shuyan; ... - Physical Review. A

The plateaus in laser-assisted recombination and high-order harmonic generation are investigated in the frequency domain. It is found that the probability amplitude of finding an electron with a given energy is given by a generalized Bessel function, which can be represented as a coherent superposition of contributions from a few electronic quantum trajectories. This concept is illustrated by comparing the spectral density of the electron with the laser-assisted recombination spectrum. On the other hand, the plateau of high-order harmonic generation reflects the spectral density of the electron at the location of the nucleus after above-threshold ionization.

Reexamination of high-energy above-threshold ionization (ATI): An alternative strong-field ATI model

Journal Article Usachenko, V; Pazdzersky, V; McIver, J - Physical Review. A

The multiphoton strong-field phenomenon of high-energy above-threshold ionization (or high-order ATI) of an isolated atomic system exposed to an intense monochromatic linearly polarized laser field is considered analytically and studied numerically within the framework of an alternative nonrelativistic strong-field approach developed earlier for theoretical treatment of high-order harmonic generation process. The related proposed alternative strong-field ATI model is fully quantum mechanical and mainly based on the Keldysh approximation combined with making use of the essential states method (along with the pole approximation). Applying together these two methods allows for representation of the total ATI amplitude in a closed and compactmore »« less

Controlling high-order harmonic generation and above-threshold ionization with an attosecond-pulse train

Journal Article Salieres, P; Villain, P; Lewenstein, M - Physical Review. A

We perform a detailed analysis of how high-order harmonic generation (HHG) and above-threshold ionization (ATI) can be controlled by a time-delayed attosecond-pulse train superposed to a strong, near-infrared laser field. In particular we show that the high-order harmonic and photoelectron intensities, the high-order harmonic plateau structure and cutoff energies, and the ATI angular distributions can be manipulated by changing this delay. This is a direct consequence of the fact that the attosecond pulse train can be employed as a tool for constraining the instant an electronic wave packet is ejected in the continuum. A change in such initial conditions stronglymore »« less

Photoelectron Angular Distributions from Above Threshold Ionization of Hydrogen Atoms in Strong Laser Fields

Journal Article Lihua, Bai; Jingtao, Zhang; Zhizhan, Xu; ... - Physical Review Letters

We apply a scattering theory of nonperturbative quantum electrodynamics to study the photoelectron angular distributions (PADs) of a hydrogen atom irradiated by linearly polarized laser light. The calculated PADs show main lobes and jetlike structure. Previous experimental studies reveal that in a set of above-threshold-ionization peaks when the absorbed-photon number increases by one, the jet number also increases by one. Our study confirms this experimental observation. Our calculations further predict that in some cases three more jets may appear with just one-more-photon absorption. With consideration of laser-frequency change, one less jet may also appear with one-more-photon absorption. The jetlike structuremore »« less

Converged three-dimensional calculations of above-threshold ionization: Angular-momentum constraints and the kinetic-energy distribution

Journal Article Blank, R; Shapiro, M - Physical Review A; (United States)

We present an application of the artificial-channel method to the calculation of multiphoton ionization rates under continuous-wave illumination conditions. We use the method to treat above-threshold ionization (ATI) of hydrogen in three dimensions with linearly and circularly polarized light at field intensities ranging from 10[sup 9] to 10[sup 14] W/cm[sup 2]. The results are compared with perturbative as well as nonperturbative calculations for short pulses and with experiments. The range of validity of the dipole approximation for ATI processes is also examined. An analysis of both the angular and angular-momentum distribution of the photoelectrons at different intensities is presented. Wemore »« less
