Ultra-intense lasers produce and manipulate plasmas, allowing to locally generate extremely high static and electromagnetic fields.This study presents a concept of an ultra-intense optical tweezer, where two counter-propagating circularly polarized intense lasers of different frequencies collide on a nano-foil.Interfering inside nitrile gloves in a bucket the foil, lasers produce a beat wave, which traps and moves plasma electrons as a thin sheet with an optically controlled velocity.The electron displacement creates a plasma micro-capacitor with an extremely strong electrostatic field, that efficiently generates narrow-energy-spread ion beams from the multi-species targets, e.g.
protons from laguna 3hp dust collector the hydrocarbon foils.The proposed ion accelerator concept is explored theoretically and demonstrated numerically with the multi-dimensional particle-in-cell simulations.
