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…

Saturable Lorentz model for fully explicit three-dimensional modeling of nonlinear optics
Charles Varin, Graeme Bart, Rhys Emms +1
Inclusion of the instantaneous Kerr nonlinearity in the FDTD framework leads to implicit equations that have to be solved iteratively. In principle, explicit integration can be ach…
