MeV femtosecond electron pulses from direct-field acceleration in low density atomic gases
Charles Varin, Vincent Marceau, Pascal Hogan-Lamarre +3
Using three-dimensional particle-in-cell simulations, we show that few-MeV electrons can be produced by focusing tightly few-cycle radially-polarized laser pulses in a low-density…

On the validity of the paraxial approximation for electron acceleration with radially polarized laser beams
Vincent Marceau, Charles Varin, Michel Piché
In the study of laser-driven electron acceleration, it has become customary to work within the framework of paraxial wave optics. Using an exact solution to the Helmholtz equation…
