Abstract

We report on the efficacy of a novel design for dielectric laser
accelerators by adding a distributed Bragg reflector (DBR) to a dual
pillar grating accelerating structure. This mimics a double-sided laser
illumination, resulting in an enhanced longitudinal electric field while
reducing the deflecting transverse effects when compared to
single-sided illumination. We improve the coupling efficiency of the
incident electric field into the accelerating mode by 57%. The 12 μm
long structures accelerate sub-relativistic 28 keV electrons with
gradients of up to 200 MeV/m in theory and 133 MeV/m in practice. This
Letter shows how lithographically produced nano-structures help to make
novel laser accelerators more efficient.
