Journal ArticleDOI
Physics of laser-driven plasma-based electron accelerators
TL;DR: In this paper, the basic physics of laser pulse evolution in underdense plasmas is also reviewed, including the propagation, self-focusing, and guiding of laser pulses in uniform density channels and with preformed density channels.
Journal ArticleDOI
High-quality electron beams from a laser wakefield accelerator using plasma-channel guiding
C. G. R. Geddes,C. G. R. Geddes,Cs. Toth,van J Jeroen Tilborg,van J Jeroen Tilborg,Eric Esarey,Carl Schroeder,David L. Bruhwiler,Chet Nieter,John R. Cary,Wim Leemans +10 more
TL;DR: A laser accelerator that produces electron beams with an energy spread of a few per cent, low emittance and increased energy (more than 109 electrons above 80 MeV) and opens the way for compact and tunable high-brightness sources of electrons and radiation.
Journal ArticleDOI
GeV electron beams from a centimetre-scale accelerator
Wim Leemans,Bob Nagler,Anthony Gonsalves,Cs. Toth,Kei Nakamura,Kei Nakamura,C.G.R. Geddes,Eric Esarey,Carl Schroeder,Simon M. Hooker +9 more
TL;DR: In this article, a high-quality electron beam with 1 GeV energy was achieved by channelling a 40 TW peak-power laser pulse in a 3.3 cm-long gas-filled capillary discharge waveguide.
Journal ArticleDOI
Multi-GeV Electron Beams from Capillary-Discharge-Guided Subpetawatt Laser Pulses in the Self-Trapping Regime
Wim Leemans,Wim Leemans,Anthony Gonsalves,Hann-Shin Mao,Kei Nakamura,Carlo Benedetti,Carl Schroeder,Cs. Toth,J. Daniels,D. E. Mittelberger,D. E. Mittelberger,Stepan Bulanov,Stepan Bulanov,Jean-Luc Vay,C. G. R. Geddes,Eric Esarey +15 more
TL;DR: A detailed comparison between experiment and simulation indicates the sensitivity in this regime of the guiding and acceleration in the plasma structure to input intensity, density, and near-field laser mode profile.
Journal ArticleDOI
Petawatt Laser Guiding and Electron Beam Acceleration to 8 GeV in a Laser-Heated Capillary Discharge Waveguide.

TL;DR: Guiding of relativistically intense laser pulses with peak power of 0.85 PW over 15 diffraction lengths was demonstrated by increasing the focusing strength of a capillary discharge waveguide using laser inverse bremsstrahlung heating.
