Electron acceleration by laser plasma wedge interaction

نویسندگان

چکیده

A new electron acceleration mechanism is identified that develops when a relativistically intense laser irradiates the wedge of an over-dense plasma. This induces diffracted electromagnetic wave with significant longitudinal electric field accelerates electrons from plasma over long distances to relativistic energies. Well collimated, highly-charged (nC) bunches energies up 100's MeV are obtained using beam $I \lambda_0^2 =3.5\times 10^{19}\,{\rm W \mu m^2/cm^2}$. Multi-dimensional particle-in-cell simulations, supported by simple analytical model, confirm efficiency and robustness proposed scheme.

Electron 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...

LASER DRIVEN ELECTRON ACCELERATION TO GeV ENERGIES IN PLASMA CHANNELS

This paper presents a brief discussion of ultra-short laser pulse propagation and laser wakefield acceleration in plasma channels. An envelope equation for the perturbed laser beam radius is given, including finite-pulse length and nonlinear effects. Angular distribution of electrons generated by the process of laser ionization and ponderomotive acceleration (LIPA) is also discussed. An example...
