Laser-based acceleration of non-relativistic electrons in a photonic structure — •John Breuer and Peter Hommelhoff — Max-Planck-Institut für Quantenoptik, Garching bei München, Germany

We present simulation results of the acceleration of non-relativistic electrons passing by a fused-silica transmission grating that is illuminated with Titanium:sapphire femtosecond laser pulses. The concept of periodic field reversal is used to directly accelerate electrons with the electromagnetic field of the laser. We have optimized the grating parameters towards maximum momentum transfer and expect accelerating gradients of up to 100 MeV/m for 27-keV electrons traveling by the grating at a distance of 30 nm. We will describe the current status of a recently started proof-of-principle experiment and discuss applications of this new form of laser-based electronic motion control.
