Self-modulated wakefield and forced laser wakefield acceleration of electrons
The interaction of intense laser pulses (power.30 TW) with underdense plasmas has been studied. In the regime where the pulse length is much longer than the plasma period (t l@2pvp ), the laser pulse is found to be self-modulated at the plasma frequency by the forward Raman scattering instability. Wavebreaking of the resulting plasma wave results in energetic electrons being accelerated to more...
متن کاملQuasi-phase-matched laser wakefield acceleration.
The energy gain in laser wakefield acceleration is ultimately limited by dephasing, occurring when accelerated electrons outrun the accelerating phase of the wakefield. We apply quasi-phase-matching, enabled by axially modulated plasma channels, to overcome this limitation. Theory and simulations are presented showing that weakly relativistic laser intensities can drive significant electron ene...
متن کاملLaser 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-plasma Wakefield Acceleration: Concepts, Tests and Premises
The concepts of laser-plasma based accelerator and injector are discussed here. Recent tests done at LOA as well as design studies of high-quality few GeV’s electron beam with low energy spread (1%) are presented. These laser-produced particle beams have a number of interesting properties and could lend themselves to applications in many fields, including medicine (radiotherapy), chemistry (rad...
