This study analyzes electron behavior during photoionization, comparing tunneling and multiphoton processes. It presents simulation results for electron distribution functions in different laser intensity regimes.

Area of Science:

  • Atomic and Molecular Physics
  • Quantum Optics
  • Plasma Physics

Background:

  • Photoionization describes the process where light removes electrons from atoms or molecules.
  • Two primary regimes exist: multiphoton ionization (low intensity) and tunneling ionization (high intensity).
  • Understanding electron behavior is crucial for controlling laser-matter interactions.

Purpose of the Study:

  • To analyze the electron distribution function in both tunneling and multiphoton ionization regimes.
  • To compare the characteristics of electrons born in each ionization process.
  • To validate theoretical models with particle-in-cell simulations.

Main Methods:

  • Solving the electron transport equation along classical equations of motion in a laser field.

  • Deriving analytical expressions for the electron distribution function in both regimes.
  • Utilizing two-dimensional particle-in-cell simulations for validation.

    • Main Results:

    • Obtained expressions for the electron distribution function in tunneling and multiphoton ionization.
    • Demonstrated that electrons have negligible velocity in tunneling ionization.
    • Showed electrons are born with fixed energy in l-photon ionization, dependent on photon energy and ionization potential.

    Conclusions:

    • The study provides a comprehensive analysis of electron behavior in different photoionization regimes.
    • Theoretical models are supported by particle-in-cell simulation results.
    • This research contributes to a deeper understanding of laser-driven electron dynamics.
