Laser wakefield acceleration by petawatt ultra-short laser pulses
An ultra-short (about 30 fs) petawatt laser pulse focused with a wide focal spot (about 100 μm) in a rarefied plasma (n0 ∼ 10 cm) excites a nonlinear plasma wakefield which can accelerate injected electrons up to the GeV energy without any pulse channelling. In these conditions, propagation of the laser pulse with an over-critical power for relativistic self-focusing is almost the same as in va...
متن کاملLaser injection of ultrashort electron pulses into Wakefield plasma waves.
A novel laser-plasma-based source of relativistic electrons is described. It involves a combination of orthogonally directed laser beams, which are focused in a plasma. One beam excites a wakefield electron plasma wave. Another locally alters the trajectory of some of the electrons in such a way that they can be accelerated and trapped by the wave. With currently available table-top terawatt la...
متن کاملMulti-MeV Electron Acceleration by Subterawatt Laser Pulses.
We demonstrate laser-plasma acceleration of high charge electron beams to the ∼10 MeV scale using ultrashort laser pulses with as little energy as 10 mJ. This result is made possible by an extremely dense and thin hydrogen gas jet. Total charge up to ∼0.5 nC is measured for energies >1 MeV. Acceleration is correlated to the presence of a relativistically self-focused laser filament accompani...
متن کاملElectron Acceleration in Relativistic Plasma Waves Generated by a Single Frequency Short-Pulse Laser
Experimental evidence for the acceleration of electrons in a relativistic plasma wave generated by Raman forward scattering (SRS-F) of a single-frequency short pulse laser are presented. A 1.053 pm, 600 fsec, 5 TW laser was focused into a gas jet with a peak intensity of 8x1017 W/cm2. At a plasma density of 2x1019 2 MeV electrons were detected and their appearance was correlated with the anti-S...
متن کاملElectron acceleration by a laser pulse in a plasma.
132 LLE Review, Volume 67 The motion of a charged particle in an electromagnetic field is a well-known paradigm of physics.1,2 Suppose that the field is associated with a laser pulse of finite extent propagating in a vacuum. As the pulse overtakes the particle, the particle gains energy and momentum at the expense of the pulse. At the peak of an intense pulse, the particle has considerable (lon...
