Attosecond Control of Relativistic Electron Bunches using Two-Colour Fields
M. Yeung, S. Rykovanov, J. Bierbach +10
Energy coupling during relativistically intense laser-matter interactions is encoded in the attosecond motion of strongly driven electrons at the pre-formed plasma-vacuum boundary.…
Modeling ultrafast shadowgraphy in laser-plasma interaction experiments
E. Siminos, S. Skupin, A. Sävert +3
Ultrafast shadowgraphy is a new experimental technique that uses few cycle laser pulses to image density gradients in a rapidly evolving plasma. It enables structures that move at…
Characterization and Application of Hard X-Ray Betatron Radiation Generated by Relativistic Electrons from a Laser-Wakefield Accelerator
Michael Schnell, Alexander Sävert, Ingo Uschmann +3
The necessity for compact table-top x-ray sources with higher brightness, shorter wavelength and shorter pulse duration has led to the development of complementary sources based on…
Direct observation of the injection dynamics of a laser wakefield accelerator using few-femtosecond shadowgraphy
A. Sävert, S. P. D. Mangles, M. Schnell +13
We present few-femtosecond shadowgraphic snapshots taken during the non-linear evolution of the plasma wave in a laser wakefield accelerator with transverse synchronized few-cycle…
Micron-scale Fast Electron Filamentation and Recirculation determined from Rear Side Optical Emission in High Intensity Laser-Solid Interactions
C. Bellei, S. R. Nagel, S. Kar +24
The transport of relativistic electrons generated in the interaction of petawatt class lasers with solid targets has been studied through measurements of the optical emission from…
