Demonstration of acceleration of relativistic electrons at a dielectric microstructure using femtosecond laser pulses.

Abstract

Acceleration of electrons using laser-driven dielectric microstructures is a promising technology for the miniaturization of particle accelerators. Achieving the desired GV m<sup>-1</sup> accelerating gradients is possible only with laser pulse durations shorter than ∼1  ps. In this Letter, we present, to the best of our knowledge, the first demonstration of acceleration of relativistic electrons at a dielectric microstructure driven by femtosecond duration laser pulses. Using this technique, an electron accelerating gradient of 690±100  MV m<sup>-1</sup> was measured-a record for dielectric laser accelerators.
