Comparison of wave-mixing processes in rarefied gas and QED vacuum using numerical simulations
Marianna Lytova, François Fillion-Gourdeau, Simon Vallières +3
We study the conditions required to distinguish laser-induced nonlinear quantum electrodynamics (QED) effects in vacuum from competing signals due to interactions of laser pulses w…
Generation of directed electron beams by tight focusing of an ultrashort IR laser in a near-critical plasma
Marianna Lytova, François Fillion-Gourdeau, Simon Vallières +4
Recent studies have demonstrated the possibility of accelerating electrons to MeV energies in ambient air using tightly focused laser configurations. In this article, we explore po…
Ambient air plasma acceleration in tightly-focused ultrashort infrared laser beams
Marianna Lytova, François Fillion-Gourdeau, Simon Vallières +3
Recent experimental and theoretical results have demonstrated the possibility of accelerating electrons in the MeV range by focusing tightly a few-cycle laser beam in ambient air.…
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…
