TLDR
In this paper, single-cycle laser pulses are used to drive high-quality MeV relativistic electron beams, thereby enabling kHz operation and dramatic downsizing of the laser system.Abstract:
Laser-plasma acceleration(1,2) is an emerging technique for accelerating electrons to high energies over very short distances. The accelerated electron bunches have femtosecond duration(3,4), making them particularly relevant for applications such as ultrafast imaging(5) or femtosecond X-ray generation(6,7). Current laser-plasma accelerators deliver 100 MeV (refs 8-10) to GeV (refs 11, 12) electrons using Joule-class laser systems that are relatively large in scale and have low repetition rates, with a few shots per second at best. Nevertheless, extending laser-plasma acceleration to higher repetition rates would be extremely useful for applications requiring lower electron energy. Here, we use single-cycle laser pulses to drive high-quality MeV relativistic electron beams, thereby enabling kHz operation and dramatic downsizing of the laser system. Numerical simulations indicate that the electron bunches are only similar to 1 fs long. We anticipate that the advent of these kHz femtosecond relativistic electron sources will pave the way to applications with wide impact, such as ultrafast electron diffraction in materials(13,14) with an unprecedented sub-10 fs resolution(15).read more

Generation, Acceleration and Measurement of Attosecond Electron Beams from Laser-Plasma Accelerators
TL;DR: In this article, the authors investigated mechanisms for ultrashort electron beam generation and acceleration in laser wakefield accelerators through particle-in-cell simulations, and showed that an optimized electron plasma injector, using upramp-assisted self-injection, and an external injection setup with the plasma stage as an energy booster to a conventionally accelerated beam are capable of providing electron bunches of few hundred attoseconds duration.
