Optical accelerator for nano-particles


A.S. Shalin, S.V. Sukhov

We suggest a model of an optical structure that allows to accelerate nanoparticles to velocities on the order of tens of centimeters per second using low intensity external optical fields. The nano-accelerator system employs metallic V-grooves which concentrate the electric field in the vicinity of their bottoms and create large optical gradient forces for the nano-particles in that groove. The conditions are found when this optical force tends to eject particles away from the groove.
