Silicon structures and 2 micron sources for DLA experiments — •Norbert Schönenberger1, Joshua McNeur1, Axel Rühl2, Jonas Hammer1, Ingmar Hartl2, and Peter Hommelhoff1 — 1Friedrich Alexander Universität Erlangen-Nürnberg, 91054 Erlangen, Deutschland — 2DESY, 22607 Hamburg, Deutschland
With the recent successful demonstration of Dielectric Laser Acceleration (DLA) of electrons using fused silica gratings and Ti:Sa lasers [1,2], we try to improve upon the current setup using silicon based structures and a 2 micron thulium fiber laser. Here, we show the modification of a commercial 5W thulium fiber laser to incorporate a Chirped Volume Bragg Grating (CVBG) for chirped pulse amplification (CPA). With this modification we achieve sub picosecond pulses in the >700nJ regime. Furthermore, we discuss the advantages of silicon based structures that will be used in conjunction with the new laser system and report on first experimental acceleration results.
