Journal ArticleDOI
Electron acceleration from the breaking of relativistic plasma waves
A. Modena,Zulfikar Najmudin,A. E. Dangor,C. E. Clayton,K. A. Marsh,C. Joshi,Victor Malka,Christopher B. Darrow,Colin N. Danson,David Neely,F. N. Walsh +10 more
TL;DR: In this article, the authors report observations of relativistic plasma waves driven to breaking point by the Raman forward-scattering instability induced by short, high-intensity laser pulses.
Journal ArticleDOI
Observation of Laser Wakefield Acceleration of Electrons
François Amiranoff,S. D. Baton,Denis Bernard,Brigitte Cros,Dominique Descamps,Fabien Dorchies,F. Jacquet,Victor Malka,Jean-Raphael Marques,G. Matthieussent,P. Miné,A. Modena,Patrick Mora,J. Morillo,Zulfikar Najmudin +14 more
TL;DR: In this article, the acceleration of electrons injected in a plasma wave generated by the laser wakefield mechanism has been observed and a maximum energy gain of 1.6 MeV has been measured and the maximum longitudinal electric field is estimated to 1.5 GV/m.
Journal ArticleDOI
Observation of Electron Energies Beyond the Linear Dephasing Limit from a Laser-Excited Relativistic Plasma Wave
Daniel Gordon,K.-C. Tzeng,C. E. Clayton,A. E. Dangor,Victor Malka,K. A. Marsh,A. Modena,Warren Mori,Patric Muggli,Zulfikar Najmudin,David Neely,Colin N. Danson,C. Joshi +12 more
TL;DR: In this article, the spatial extent of the plasma wave and the spectrum of the accelerated electrons are simultaneously measured when the relativistic plasma wave associated with Raman forward scattering of an intense laser beam reaches the wave breaking limit.
Journal ArticleDOI
Plasma Wave Generation in a Self-Focused Channel of a Relativistically Intense Laser Pulse
C. E. Clayton,K.-C. Tzeng,Daniel Gordon,Patric Muggli,Warren Mori,C. Joshi,Victor Malka,Zulfikar Najmudin,A. Modena,David Neely,A. E. Dangor +10 more
TL;DR: In this paper, Schlieren et al. showed that relativistically propagating plasma waves are excited over the entire length of the channel, up to 12 Rayleigh lengths (≈4mm).
Journal ArticleDOI
Observation of Raman forward scattering and electron acceleration in the relativistic regime
A. Modena,Zulfikar Najmudin,A. E. Dangor,C. E. Clayton,K. A. Marsh,Chan Joshi,Victor Malka,Christopher B. Darrow,Colin N. Danson +8 more
TL;DR: Raman forward scattering (RFS) is observed in the interaction of a high intensity (>10/sup 18/ W/cm/sup 2/) short pulse (<1 ps) laser with an underdense plasma (n/sub e//spl sim/10/Sup 19/ cm/sup -3/) Electrons are trapped and accelerated up to 44 MeV by the high-amplitude plasma wave produced by RFS as mentioned in this paper.
