Attosecond electron bunches from a nanofiber driven by Laguerre-Gaussian laser pulses

Abstract Generation of attosecond bunches of energetic electrons offers significant potential from ultrafast physics to novel radiation sources. However, it is still a great challenge to stably produce such electron beams with lasers, since the typical subfemtosecond electron bunches from laser-plas...
