Dephasingless laser wakefield acceleration in a plasma waveguide
J. P. Palastro, K. G. Miller, C. D. Arrowsmith +10
Laser wakefield accelerators (LWFAs) provide extremely large accelerating gradients for compact electron accelerators and photon sources but are limited by dephasing, where trapped…
Space-time beams with tunable orbital group velocity toward plasma superradiance
Gabrielle Vaz, Rafael Almeida, Pablo San Miguel Claveria +7
Light springs are space-time beams that have a helical wavepacket. Due to this special property, light springs result into a rotating pulse when intercepting a plane lying orthogon…
Simulation Design for Velocity-Controlled Spatio-Temporal Drivers in Laser Wakefield Acceleration
Chiara Badiali, Rafael Almeida, Thales Silva +1
Velocity-controlled spatio-temporal (ST) laser drivers offer a route to tailoring laser-plasma interactions by allowing the velocity of the intensity peak to be controlled independ…
Plasma Accelerator For Decaying Particles
Chiara Badiali, Rafael Almeida, Bernardo Malaca +3
We introduce a plasma wakefield acceleration scheme capable of boosting initially subrelativistic particles to relativistic velocities within millimeter-scale distances. A sublumin…
Universal structure of propagation-invariant optical pulses
Rafael Russo Almeida, Dillon Ramsey, Ayman F. Abouraddy +2
Space-time structuring of light - where spatial and temporal degrees of freedom are deliberately coupled and controlled - is an emerging area of optics that enables novel configura…
