Abstract

Slowly evolving, regularly spaced patterns have been observed in proton projection images of plasma channels drilled by intense (> or approx. 10{sup 19} W cm{sup -2}) short ({approx}1 ps) laser pulses propagating in an ionized gas jet. The nature and geometry of the electromagnetic fields generating such patterns have been inferred by simulating the laser-plasma interaction and the following plasma evolution with a two-dimensional particle-in-cell code and the probe proton deflections by particle tracing. The analysis suggests the formation of rows of magnetized soliton remnants, with a quasistatic magnetic field associated with vortexlike electron currents resembling those of magnetic vortices.

Electron vortices produced by ultraintense laser pulses

Journal Article Bulanov, S; Lontano, M; Esirkepov, T; ... - Physical Review Letters

Particle-in-cell simulations show that finite width and length laser pulses subject to relativistic self-focusing propagate in an underdense plasma in a {open_quote}{open_quote}bullet{close_quote}{close_quote} shape and produce a quasistatic magnetic field. This field remains behind the pulse and forms a magnetic wake associated with a row of electron fluid vortices which are described by the Hasegawa-Mima equation. The vortices propagate much more slowly than the pulse and evolve into an antisymmetric configuration which is shown to be stable when the distance between its vortices is greater than the electron skin depth. {copyright} {ital 1996 The American Physical Society.}

Observation of a strong correlation between electromagnetic soliton formation and relativistic self-focusing for ultra-short laser pulses propagating through an under-dense plasma

Journal Article Bin, Zhu; Yuchi, Wu; Kegong, Dong; ... - Physics of Plasmas

A strong correlation is observed between the formation of electromagnetic solitons, generated during the interaction of a short intense laser pulse (30 fs, {approx}10{sup 18} W/cm{sup 2}) with a rarefied (<0.1n{sub c}) plasma, and pulse self-focusing. Pulse defocusing, which occurs after soliton generation, results in laser-pulse energy depletion. The role of stimulated Raman scattering in soliton generation is analyzed from 2D particle-in-cell simulations. An observed relationship between initial plasma density and soliton generation is presented that might have relevance to wake-field accelerators.

Quantum ring solitons and nonlocal effects in plasma wake field excitations

Journal Article Fedele, R; Tanjia, F; De Nicola, S; ... - Physics of Plasmas

A theoretical investigation of the quantum transverse beam motion for a cold relativistic charged particle beam travelling in a cold, collisionless, strongly magnetized plasma is carried out. This is done by taking into account both the individual quantum nature of the beam particles (single-particle uncertainty relations and spin) and the self consistent interaction generated by the plasma wake field excitation. By adopting a fluid model of a strongly magnetized plasma, the analysis is carried out in the overdense regime (dilute beams) and in the long beam limit. It is shown that the quantum description of the collective transverse beam dynamicsmore »« less

Observation of plasma density dependence of electromagnetic soliton excitation by an intense laser pulse

Journal Article Sarri, G; Kar, S; Kourakis, I; ... - Physics of Plasmas

The experimental evidence of the correlation between the initial electron density of the plasma and electromagnetic soliton excitation at the wake of an intense (10{sup 19} W/cm{sup 2}) and short (1 ps) laser pulse is presented. The spatial distribution of the solitons, together with their late time evolution into post-solitons, is found to be dependent upon the background plasma parameters, in agreement with published analytical and numerical findings. The measured temporal evolution and electrostatic field distribution of the structures are consistent with their late time evolution and the occurrence of multiple merging of neighboring post-solitons.

Particle-in-cell simulations of ultra intense laser pulses propagating through overdense plasma for fast-ignitor and radiography applications

Journal Article Lasinski, B; Langdon, A; Hatchett, S; ... - Physics of Plasmas

Zohar (two-dimensions, particle-in-cell) [C. K. Birdsall and A. B. Langdon, {ital Plasma Physics via Computer Simulation} (McGraw{endash}Hill, New York, 1985)] simulations of ultra intense laser beams boring into overdense plasmas whose parameters are guided by the fast-ignitor concept and radiography applications are presented. Complex low frequency magnetic field structures, narrow channel formation, and beam deflection are all evident. Particle tracking diagnostics elucidate the nature of the currents that produce and interact with these static magnetic fields which are larger than 10{sup 9} G for simulations at 10{sup 21} W/cm{sup 2} in a 50n{sub c} plasma.
