Dielectric laser acceleration of nonrelativistic electrons at a single fused silica grating structure: Experimental part

Abstract: Recently, our group has demonstrated dielectric laser acceleration of nonrelativistic electrons at a scalable fused silica grating [J. Breuer and P. Hommelhoff, Phys. Rev. Lett. 111, 134803 (2013)]. This represents a demonstration of the inverse Smith-Purcell effect in the optical regime. The third spatial harmonic of the grating, which is excited by Titanium:sapphire laser pulses, synchronously accelerates 28 keV electrons derived from an electron microscope column. We observe a maximum acceleration gradient … Show more

“…Several recently demonstrated candidate DLA structures consist of a planar dielectric structure that is periodic along the particle axis with either an semi-open geometry or a narrow (micron to sub-micron) vacuum gap in which the particles travel [2][3][4][5][6][7][8][9]. These structures are then sideilluminated by laser pulses.…”

“…In previous works, candidate DLA geometries were optimized for maximum acceleration gradient by scanning through parameters of a specified structure geometry [2][3][4][5][6][7][8][9]. However, this strategy has limited potential to produce higher acceleration gradient structures because it only searches a small portion of the total design space.…”
