Effect of external magnetic field on wakefield generation in underdense plasma slab using backward semi-Lagrangian Vlasov code

open access: yesPhysical Review Accelerators and Beams, 2019
Laser wakefield excitation in the interaction of femtosecond laser pulse with an underdense thin magnetized plasma slab is studied by one dimensional relativistic Vlasov-Maxwell system of equations.

Two-Surface Wave Decay [PDF]

open access: yes, 2002
Using an analytical model we discuss the parametric excitation of pairs of electron surface waves (ESW) in the interaction of an ultrashort, intense laser pulse with an overdense plasma which has a step-like density profile.

Plasmoid ejection and secondary current sheet generation from magnetic reconnection in laser-plasma interaction. [PDF]

open access: yesPhysical Review Letters, 2012
Reconnection of the self-generated magnetic fields in laser-plasma interaction was first investigated experimentally by Nilson et al. [Phys. Rev. Lett. 97, 255001 (2006)] by shining two laser pulses a distance apart on a solid target layer.

Quantum anti-quenching of radiation from laser-driven structured plasma channels [PDF]

open access: yes, 2020
We demonstrate that in the interaction of a high-power laser pulse with a structured solid-density plasma-channel, clear quantum signatures of stochastic radiation emission manifest, disclosing a novel avenue to studying the quantized nature of photon ...

Note: femtosecond laser micromachining of straight and linearly tapered capillary discharge waveguides [PDF]

open access: yes, 2011
Gas-filled capillary discharge waveguides are important structures in laser-plasma interaction applications, such as the laser wakefield accelerator. We present the methodology for applying femtosecond laser micromachining in the production of capillary ...

Quasimonoenergetic electron beams produced by colliding cross-polarized laser pulses in underdense plasmas

open access: yes, 2008
The interaction of two laser pulses in an underdense plasma has proven to be able to inject electrons in plasma waves, thus providing a stable and tunable source of electrons. Whereas previous works focused on the "beatwave" injection scheme in which two

High density ultrashort relativistic positron beam generation by laser-plasma interaction

open access: yes, 2016
A mechanism of high energy and high density positron beam creation is proposed in ultra-relativistic laser-plasma interaction. Longitudinal electron self-injection into a strong laser field occurs in order to maintain the balance between the ...

Transition from Coherent to Stochastic electron heating in ultrashort relativistic laser interaction with structured targets

open access: yesScientific Reports, 2017
Relativistic laser interaction with micro- and nano-scale surface structures enhances energy transfer to solid targets and yields matter in extreme conditions. We report on the comparative study of laser-target interaction mechanisms with wire-structures
