Special Issue Information

Dear Colleagues,

Laser–plasma interactions and applications cover the fundamental and applied aspects of high-power laser plasma physics. These include studies of the interaction of laser radiation with matter under extreme conditions (the effect of a radiation field on excitation and ionization in non-LTE high energy density plasmas, energetic electron generation and transport in laser plasma, shock waves and equations of state related to laser plasma, etc.), inertial confinement fusion research, laser plasma particles and radiation sources (laser plasma accelerators, coherent light sources in x-ray and extreme ultraviolet, generation of femtosecond and attosecond radiation pulses, etc.).

In this Special Issue titled “Laser–Plasma Interactions and Applications”, we invite submissions reporting new results in experiments, theory and numerical simulations, as well as papers discussing recent and potential applications. Topics of interest generally include (but are not limited to):

  • High-intensity lasers;
  • Laser-produced plasmas;
  • Plasma physics;
  • Electron beams;
  • X-ray emission;
  • Plasma diagnostics;
  • Plasma simulations;
  • Inertial confinement fusion;
  • Plasma sources;
  • Solid state targets;
  • Gas jet targets.

We experimentally investigated the accelerated proton beam characteristics such as maximum energy and number by varying the incident laser parameters. For this purpose, we varied the laser energy, focal spot size, polarization, and pulse duration. The proton spectra were recorded using a single-shot Thomson parabola spectrometer equipped with a microchannel plate and a high-resolution charge-coupled device with a wide detection range from a few tens of keV to several MeV. The outcome of the experimental findings is discussed in detail and compared to other theoretical works. Full article

Wave packet molecular dynamics (WPMD) has recently received a lot of attention as a computationally fast tool with which to study dynamical processes in warm dense matter beyond the Born–Oppenheimer approximation. These techniques, typically, employ many approximations to achieve computational efficiency while implementing semi-empirical scaling parameters to retain accuracy. We investigated three of the main approximations ubiquitous to WPMD: a restricted basis set, approximations to exchange, and the lack of correlation. We examined each of these approximations in regard to atomic and molecular hydrogen in addition to a dense hydrogen plasma. We found that the biggest improvement to WPMD comes from combining a two-Gaussian basis with a semi-empirical correction based on the valence-bond wave function. A single parameter scales this correction to match experimental pressures of dense hydrogen. Ultimately, we found that semi-empirical scaling parameters are necessary to correct for the main approximations in WPMD. However, reducing the scaling parameters for more ab-initio terms gives more accurate results and displays the underlying physics more readily. Full article

In experimental studies of laser-plasma interactions, the laser radiation can exist inside plasma regions where the electron density is below the critical density (“underdense” plasma), as well as at the surface of the critical density. The surface of the critical density could exhibit a rich physics. Namely, the incident laser radiation can get converted in transverse electromagnetic waves of significantly higher amplitudes than the incident radiation, due to various nonlinear processes. We proposed a diagnostic method based on the laser-produced satellites of hydrogenic spectral lines in plasmas. The method allows measuring both the laser field (or more generally, the field of the resulting transverse electromagnetic wave) and the opacity from experimental spectrum of a hydrogenic line exhibiting satellites. This spectroscopic diagnostic should be useful for a better understanding of laser-plasma interactions, including relativistic laser-plasma interactions. Full article
