In this paper, an intense electromagnetic pulse can create a weak of plasma oscillations through the action of the nonlinear ponderomotive force, and electrons trapped in the wake can be accelerated to high energy.Abstract:
An intense electromagnetic pulse can create a weak of plasma oscillations through the action of the nonlinear ponderomotive force. Electrons trapped in the wake can be accelerated to high energy. Existing glass lasers of power density ${10}^{18}$W/${\mathrm{cm}}^{2}$ shone on plasmas of densities ${10}^{18}$ ${\mathrm{cm}}^{\ensuremath{-}3}$ can yield gigaelectronvolts of electron energy per centimeter of acceleration distance. This acceleration mechanism is demonstrated through computer simulation. Applications to accelerators and pulsers are examined.read more

TL;DR: In this article, a generalization of FDH/FDS (termed frequency domain tomography (FDT)) is proposed to record a time sequence of quasi-static snapshots, like the frames of a movie, of the wake structure as it propagates through the plasma.

Novel techniques of laser acceleration: from structures to plasmas
TL;DR: Two novel techniques of laser particle acceleration are discussed, based on a solid-state accelerating structure powered by a short pulse CO2 laser and a laser beatwave to excite a high-amplitude plasma wave, which accelerates relativistic particles.

TL;DR: In this article, the role of plasma channels as waveguides for laser-wakefield accelerators is discussed in terms of the results of experiments performed with the Astra-Gemini laser, numerical simulations using the code WAKE, and the theory of self-focusing and self-guiding of intense laser beams.
