Title: Dynamics of emitting electrons in strong laser fields

Abstract

A new derivation of the motion of a radiating electron is given, leading to a formulation that differs from the Lorentz-Abraham-Dirac equation and its published modifications. It satisfies the proper conservation laws. Particularly, it conserves the generalized momentum, eliminating the symmetry-breaking runaway solution. The equation allows a consistent calculation of the electron current, the radiation effect on the electron momentum, and the radiation itself, for a single electron or plasma electrons in strong electromagnetic fields. The equation is then applied to a simulation of a strong laser pulse interaction with a plasma target. Some analytical solutions are also provided.

  • Electron-ion collisions in the presence of a strong laser field lead to a distribution of fast electrons with maximum energy E{sub max}=(k{sub 0}+2v{sub 0}){sup 2}/2(a.u.), where k{sub 0} is the impact and v{sub 0} the quiver velocity of the electron. The energy spectrum is calculated by two approaches: (1) The time-dependent Schroedinger equation is numerically solved for wave packet scattering from a one-dimensional softcore Coulomb potential. Multiphoton energy spectra are obtained demonstrating a separation of the energy spectrum into an exponential distribution for transmission and a plateau distribution for reflection. (2) The energy spectrum is analytically calculated in the frameworkmore » of classical instantaneous Coulomb collisions with random impact parameters and random phases of the laser field. An exact solution for the energy spectrum is obtained from which the fraction of fast electrons in the plateau region can be estimated.« less
  • Experiments on strong shock excitation in spherical plastic targets conducted at the Omega Laser Facility are interpreted with the radiation–hydrodynamics code CHIC to account for parametric instabilities excitation and hot-electron generation. The effects of hot electrons on the shock-pressure amplification and upstream preheat are analyzed. In this study, it is demonstrated that both effects contribute to an increase in shock velocity. Comparison of the measured laser reflectivity and shock flash time with numerical simulations make it possible to reconstitute the time history of the ablation and shock pressures. Finally, consequences of this analysis for the shock-ignition target design are discussed.
  • The behavior of atoms submitted to intense electromagnetic fields is a subject of wide interest and active research. Much of the knowledge in this field is provided by studying the ionization dynamics, the energy and momentum of the photoelectrons, and the spectrum of emitted photons. Multiphoton ionization (MPI) is the process by which an atom is ionized by simultaneous absorption of several photons. The number of photons absorbed is in general even larger than the minimum required by energy conservation. The excess energy can be transferred to the photoelectron whose energy spectrum is composed of a series of lines separatedmore » by the photon energy. This process is known as above-threshold ionization (ATI). Alternately, the electron can be recaptured, emitting a series of energetic photons at odd harmonic frequencies of the driving field, dubbed optical harmonic generation (OHG). The particular topics studied in this paper are: Transient Resonances and Excited State Population Trapping; Evolution from Multiphoton to Tunneling; Electron Energy Distributions; Effects of Rescattering on the Photoelectron Energy and Momentum; {open_quotes}Direct{close_quotes} Channel in Multiphoton Double Ionization; {open_quotes}Nonsequential{close_quotes} Channel in Tunneling Double Ionization; and Nonsequential Rate.« less
  • Ionization and/or fragmentation of large organic molecules in strong laser fields can be quantitatively understood as a transition from adiabatic to nonadiabatic dynamics of the electronic degrees of freedom. Measurements of fragmentation patterns demonstrate regular trends as a function of the size and electronic structure of a molecule. A theoretical model is presented that agrees quantitatively with the measurements for a series of polycyclic aromatic molecules.
  • We use a train of sub-200 attosecond extreme ultraviolet (XUV) pulses with energies just above the ionization threshold in argon to create a train of temporally localized electron wave packets. We study the energy transfer from a strong infrared (IR) laser field to the ionized electrons as a function of the delay between the XUV and IR fields. When the wave packets are born at the zero crossings of the IR field, a significant amount of energy ({approx}20 eV) is transferred from the field to the electrons. This results in dramatically enhanced above-threshold ionization in conditions where the IR fieldmore » alone does not induce any significant ionization. Because both the energy and duration of the wave packets can be varied independently of the IR laser, they are valuable tools for studying and controlling strong-field processes.« less
