Relativistic electrons from vacuum laser acceleration using tightly focused radially polarized beams
Jeffrey Powell, Spencer W. Jolly, Simon Vallières +7
We generate a tabletop pulsed relativistic electron beam at 100 Hz repetition rate from vacuum laser acceleration (VLA) by tightly focusing a radially polarized beam into a low-den…

Scattered field formalism in the particle-in-cell method for plasma acceleration in tightly focused ultrashort laser beams
M. Lytova, F. Fillion-Gourdeau, S. Vallières +2
The scattered field formalism is combined to the particle-in-cell method to model relativistic laser-plasma dynamics in complex field configurations. Despite the strong nonlinearit…
