Abstract We studied the effect of target thickness on relativistic self-induced transparency (RSIT) and observed that, for subwavelength targets, the corresponding threshold target density (beyond which the target is opaque to an incident laser pulse of given intensity) increases. The accelerating longitudinal electrostatic field created by RSIT from the subwavelength target is then used to accelerate the ions from a thin, low density layer behind the main target to ~100 MeV using a 6 cycle…

Chirp assisted ion acceleration via relativistic self-induced transparency

We study the effect of the chirped laser pulse on the transmission and associated ion acceleration by the sub-wavelength target. In the chirped laser pulses, the pulse frequency has a temporal

Laser pulse dispersion in underdense plasma and associated ion acceleration by relativistic self-induced transparency

The propagation of laser pulses in the underdense plasma is a very crucial aspect of the laser-plasma interaction process. In this work, we explored the two regimes of laser propagation in the



Enhanced laser-driven ion acceleration in the relativistic transparency regime.

An unprecedented maximum energy of 185 MeV (15 MeV/u) for fully ionized carbon atoms is observed at the optimum thickness of 30 nm, leading to strong volumetric heating of the classically overdense electron population in the bulk of the target.

There exists an inherent limit of the induced transparency on the density of the overdense plasma in order to obtain a stationary physical solution, and it is found that the striction nonlinearity tends to create a strong peaking of the plasma electron density.

Electromagnetic energy penetration in the self-induced transparency regime of relativistic laser-plasma interactions.

Two qualitatively different scenarios for the penetration of relativistically intense laser radiation into an overdense plasma, accessible by self-induced transparency, are presented. In the first

Relativistic self-induced transparency effect during ultraintense laser interaction with overdense plasmas: Why it occurs and its use for ultrashort electron bunch generation

A novel explanation of the relativistic self-induced transparency effect during superintense laser interaction with an overdense plasma is proposed. It was studied analytically and verified with

Characterization of high-intensity laser propagation in the relativistic transparent regime through measurements of energetic proton beams.

Simulations show that the laser beam penetrates deeper into the target due to its relativistic propagation and results in greater collimation of the ensuing hot electrons, which results in the rear surface accelerating electric field being larger, increasing the efficiency of the acceleration.

Radiation pressure acceleration of ultrathin foils

The acceleration of sub-wavelength, solid-density plasma foils by the ultraintense radiation pressure of circularly polarized laser pulses is investigated analytically and with simulations. An

Laser ponderomotive force at superhigh intensities provides an efficient ion acceleration in bulk dense targets and evacuates a channel enabling further laser beam propagation. The developed

The interaction of a circularly polarized laser pulse with a mixed solid target containing two species of ions is studied by particle in cell simulations and analytical model. After the interaction

Laser ion acceleration using a solid target coupled with a low-density layer.

This work investigates by particle-in-cell simulations the laser-plasma interaction and the proton acceleration in multilayer targets where a low-density ("near-critical") layer of a few-micron thickness is added on the illuminated side of a thin, high-density layer.
