TL;DR: The radiation produced when an intense laser interacts with a solid target could provide a cheaper source of X-rays to synchrotrons and free-electron lasers.
Journal ArticleDOI

TL;DR: It is shown that 1–100 J pump pulses can amplify picojoule seed pulses to nearly joule level, and the extremely high gain leads to significant amplification of backscattered radiation from “noise”, arising from stochastic plasma fluctuations that competes with externally injected seed pulses.
Journal ArticleDOI
Radiation sources based on laser-plasma interactions.

TL;DR: This work will discuss how a laser-driven plasma wakefield accelerator can be used to produce radiation with unique characteristics over a very large spectral range.
Journal ArticleDOI
High quality electron beams from a laser wakefield accelerator
S. M. Wiggins,Richard Shanks,Riju C. Issac,Gregor H. Welsh,Maria Pia Anania,Enrico Brunetti,Gregory Vieux,Silvia Cipiccia,Bernhard Ersfeld,M. R. Islam,R. T. L. Burgess,Grace Manahan,Constantin Aniculaesei,W. A. Gillespie,A. M. MacLeod,Dino A. Jaroszynski +15 more
TL;DR: Very stable, high quality electron beams (current ∼ 10 kA, energy spread < 1%, emittance ∼ 1π mm mrad) have been generated in a laser-plasma accelerator driven by 25 TW femtosecond laser pulses as mentioned in this paper.
Journal ArticleDOI
Near-threshold electron injection in the laser-plasma wakefield accelerator leading to femtosecond bunches

TL;DR: In this paper, it was shown that the localized charge density build-up in the sheath crossing region at the rear of the bubble has the effect of increasing the accelerating potential to above a critical value, which explains why single or multiple ultra short electron bunches with little dark current are formed in the first bubble.
