Scientists discovered enhanced absorption of ultrashort superintense laser beams in clustered matter. Nonlinear oscillations and electron-ion collisions significantly boost absorption, even at moderate laser intensities.

Area of Science:

  • Plasma Physics
  • Laser-Matter Interactions
  • Nonlinear Optics

Background:

  • Enhanced absorption of ultrashort superintense laser beams in clustered matter is observed.
  • Existing particle-in-cell simulations confirm this phenomenon, but underlying physics remain unclear.
  • Linear resonance absorption is not applicable when plasma frequency exceeds laser frequency.

Purpose of the Study:

  • To elucidate the physical mechanisms behind enhanced laser absorption in clustered matter.
  • To investigate the role of nonlinear oscillations and electron-ion collisions in absorption enhancement.
  • To explain excellent absorption at moderate laser intensities.

Main Methods:

  • Theoretical analysis of laser-matter interactions in clustered environments.

  • Investigation of nonlinear plasma oscillations and their resonance with laser frequency.
  • Explicit analysis of coherent superposition of electron-ion collisions in ionized clusters.

    • Main Results:

    • Nonlinear oscillations in plasma enter resonance with laser frequency due to restoring force lowering in Coulomb systems.
    • Excellent absorption is achieved even at moderate laser intensities.
    • Coherent superposition of electron-ion collisions leads to several orders of magnitude enhancement in collisional absorption.

    Conclusions:

    • Nonlinear plasma dynamics and electron-ion collisions are key mechanisms for enhanced laser absorption in clustered matter.
    • The findings clarify previously ambiguous physical processes in laser-matter interactions.
    • This research offers insights into optimizing laser absorption for various applications.
