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…
High Dose-Rate Ionizing Radiation Source from Tight Focusing in Air of a mJ-class Femtosecond Laser
S. Vallières, J. Powell, T. Connell +7
Ultrashort electron beams with femtosecond to picosecond bunch durations offer unique opportunities to explore active research areas ranging from ultrafast structural dynamics to u…
Photoexcitation Circular Dichroism in Chiral Molecules
S. Beaulieu, A. Comby, D. Descamps +13
Chirality is ubiquitous in nature and fundamental in science, from particle physics to metamaterials.The most established technique of chiral discrimination - photoabsorption circu…
Relaxation Dynamics in Photoexcited Chiral Molecules Studied by Time-Resolved Photoelectron Circular Dichroism: Toward Chiral Femtochemistry
Antoine Comby, Samuel Beaulieu, Martial Boggio-Pasqua +8
Unravelling the main initial dynamics responsible for chiral recognition is a key stepin the understanding of many biological processes. However this challenging task requires a se…
