Centrifugal motion of an optically levitated particle in a rotating beam

Posted on 22.09.2021 - 18:34
Levitated optomechanical systems experience a tremendous development on detecting weak force and torque with translational and torsional motion of the levitated particle. Here, the levitated optomechanical system is established on a rotating platform, and the centrifugal motion of the particle is observed after rotating the optical platform. The centrifugal displacement of the particle is experimentally proved to show a quadratic function relation with the rotation speed, and the stiffness of the trap and the mass of the levitated particle are obtained from it separately. Furthermore, a particle with rotation, revolution and centrifugal translation coupling is investigated in this system. We demonstrate that it is possible to detect some new physical quantities, such as rotation and celestial movement, that has not been realized before with the centrifugal motion.
