A tabletop, ultrashort pulse photoneutron source driven by electrons from laser wakefield acceleration

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...

Acceleration of Electrons in a Self-Modulated Laser Wakefield

Acceleration of electrons in a self-modulated laser-wake eld is investigated. The generated electron beam is oberved to have a multi-component beam pro le and its energy distribution undergoes discrete transitions as the conditions are varied. These features can be explained by simple simulations of electron propagation in a 3-D plasma wave. Understanding the dynamics of electron acceleration i...

Simulation of laser wakefield acceleration of an ultrashort electron bunch.

The dynamics of the acceleration of a short electron bunch in a strong plasma wave excited by a laser pulse in a plasma channel is studied both analytically and numerically in slab geometry. In our simulations, a fully nonlinear, relativistic hydrodynamic description for the plasma wave is combined with particle-in-cell methods for the description of the bunch. Collective self-interactions with...
