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

TL;DR: In this article , the beam transmission of MeV ultrafast electron diffraction (UED) was investigated using laser wakefield accelerator (LWFA) and double bend achromat, and the beamline isochronous such that the arrival time jitter induced by the shot-to-shot energy fluctuation can be eliminated.

TL;DR: In this paper, the carrier-envelope phase (CEP) of the light-matter interactions is studied in the few-femtosecond regime, where the electric field can exhibit a strong dependence not only on the intensity profile of the pulses but also on their electric field.

Photon Acceleration from Optical to XUV
TL;DR: In this paper , phase-matching conditions for a 1D nonlinear plasma wake with an electron beam driver were derived. But the authors did not consider the effect of the density of the wake.

GeV-scale accelerators driven by plasma-modulated pulses from kilohertz lasers
TL;DR: In this paper, the temporal phase of a long, high-energy driving laser pulse can be modulated periodically by co-propagating it with low-amplitude plasma wave driven by a short, low-energy seed pulse.
