Generation of 'Super-Ponderomotive' Electrons due to a non-Wakefield interaction between a Laser Pulse and a Longitudinal Electric Field

A. P. L. Robinson, A. V. Arefiev, D. Neely

It is shown that electrons with momenta exceeding the `free electron' limit of $m_{e}c{a}_0^2/2$ can be produced when a laser pulse and a longitudinal electric field interact with an e…
