Optical tweezers have become powerful tools in many areas. By transferring light momentum from photons to micro- and nano-particles, one could immobilize submicron particles, transport them and also measure sub-picoNewton forces. In this paper we show by utilizing the angular momentum of a circularly polarized light, metallic nano particles rotate. Rotation speed depends to laser power and particle shape and size. Here, we show that rotation speed for round shape particle raise up to few kHz.
Keywords: Optical tweezers, Metallic nano particles, Optical torque, Angular momentum
