Resonant excitation of plasma waves in a plasma channel
Aimee J. Ross, James Chappell, Johannes J. van de Wetering +14
We demonstrate resonant excitation of a plasma wave by a train of short laser pulses guided in a pre-formed plasma channel, for parameters relevant to a plasma-modulated plasma acc…
All-optical GeV electron bunch generation in a laser-plasma accelerator via truncated-channel injection
A. Picksley, J. Chappell, E. Archer +10
We describe a simple scheme, truncated-channel injection, to inject electrons directly into the wakefield driven by a drive pulse guided by an all-optical plasma channel. We use th…
Multi-GeV electron bunches from an all-optical laser wakefield accelerator
B. Miao, J. E. Shrock, L. Feder +8
We present the first demonstration of multi-GeV laser wakefield acceleration in a fully optically formed plasma waveguide, with an acceleration gradient as high as 25 GeV/m. The gu…
Meter-Scale, Conditioned Hydrodynamic Optical-Field-Ionized Plasma Channels
A. Picksley, A. Alejo, R. J. Shalloo +9
We demonstrate through experiments and numerical simulations that low-density, low-loss, meter-scale plasma channels can be generated by employing a conditioning laser pulse to ion…
Guiding of high-intensity laser pulses in 100mm-long hydrodynamic optical-field-ionized plasma channels
A. Picksley, A. Alejo, J. Cowley +11
Hydrodynamic optically-field-ionized (HOFI) plasma channels up to 100mm long are investigated. Optical guiding is demonstrated of laser pulses with a peak input intensity of $6\tim…
Multi-MeV electron acceleration by sub-terawatt laser pulses
A. J. Goers, G. A. Hine, L. Feder +3
We demonstrate laser-plasma acceleration of high charge electron beams to the ~10 MeV scale using ultrashort laser pulses with as little energy as 10 mJ. This result is made possib…
