▎ 摘　　要

NOVELTY - The laser propulsion method involves placing a graphene material in rare gas with air pressure not higher than 103Pa. The graphene material in the rare gas is irradiated with a laser beam to realize the laser propulsion of the graphene material in the rare gas. The rare gas includes air, argon or nitrogen. The size of the graphene material is nano-scale, micron-scale, millimeter-scale, centimeter-scale or meter-scale. The quality and volume of the graphene material are determined by the spot size of the laser beam, the laser power density, the air pressure of the rare gas and the type of the rare gas. The laser beam of the invention is a continuous laser or a pulsed laser. The wavelength is UV to infrared band. The laser propulsion distance of the graphene material in the rare gas reaches more than meters. USE - Laser propulsion method of graphene in rare gas. ADVANTAGE - The graphene material has no loss or damage in the laser propulsion process, and realizes continuous light propulsion without any fuel supplement. Laser irradiation is used to directly push the graphene material in rare gas by laser beam, and graphene as carrier directly pushes other materials, so that non-contact push of graphene or other related objects is realized without any fuel, and the driving force is far greater than light pressure. The overall process of the method is simple, efficient, and environmentally-friendly and has a broad application prospect. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of a working principle of the graphene laser propulsion technology in rare gas.
