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…

Harmonic Generation from Relativistic Plasma Surfaces in Ultra-Steep Plasma Density Gradients
Christian Rödel, Daniel an der Brügge, Jana Bierbach +19
Harmonic generation in the limit of ultra-steep density gradients is studied experimentally. Observations demonstrate that while the efficient generation of high order harmonics fr…
