Plasma waveguides for high-intensity laser pulses
J. E. Shrock, B. Miao, E. Rockafellow +1
Fundamental to many applications of laser pulses in science and technology is an extended interaction length with matter that significantly exceeds the distance over which the puls…
Excitation of Giant Surface Waves During Laser Wake Field Acceleration
Travis Garrett, Christopher Pieronek, E. Rockafellow +7
We have detected the presence of very high intensity surface waves that are excited during plasma waveguided laser wakefield acceleration. Wakefield acceleration can be enchanced b…
Longitudinal shaping of plasma waveguides using diffractive axicons for laser wakefield acceleration
N. Tripathi, B. Miao, A. Sloss +4
New techniques for the optical generation of plasma waveguides -- optical fibres for ultra-intense light pulses -- have become vital to the advancement of multi-GeV laser wakefield…
Matched Guiding and Controlled Injection in Dark-Current-Free, 10-GeV-Class, Channel-Guided Laser Plasma Accelerators
A. Picksley, J. Stackhouse, C. Benedetti +12
We measure the high intensity laser propagation throughout meter-scale, channel-guided LPAs by adjusting the length of the plasma channel on a shot-by-shot basis, showing high qual…
Benchmarking of hydrodynamic plasma waveguides for multi-GeV laser-driven electron acceleration
B. Miao, E. Rockafellow, J. E. Shrock +3
Hydrodynamic plasma waveguides initiated by optical field ionization (OFI) have recently become a key component of multi-GeV laser wakefield accelerators. Here, we present the most…
