Synchronous Acceleration in the Optical Regime: Recent Results and Future Directions of Dielectric Laser Acceleration — •Joshua McNeur1, Jonas Hammer1, Ang Li1, Norbert Schönberger1, Alexander Tafel1, and Peter Hommelhoff1,21Department of Physics, Friedrich-Alexander-Universität Erlangen Nürnberg, Staudtstr. 1, D-91058 Erlangen, Germany — 2Max Planck Institute of Quantum Optics, Hans-Kopfermann-Str. 1, D-85748 Garching, Germany

Dielectric laser acceleration scales phase synchronous acceleration – proposed by Widerøe approximately 90 years ago [1] and successfully employed within multitudes of accelerator facilities – to the optical regime. Within the last year, acceleration has been demonstrated in this new regime on multiple fronts (at different electron energies, laser wavelengths and laser pulse energies) [2,3]. The theory [4] and recent demonstration of Dielectric Laser Acceleration of subrelativistic electrons is reviewed. Future directions of the FAU DLA project including proton acceleration, use of a 2 micron Th fiber laser, deflecting and focusing geometries and a laser-triggered electron source, are discussed.
