Damping of optically levitated particles by feedback and beam shaping










Image Number 2 for United States Patent #4092535.

An improvement on an optical levitation device is disclosed for damping perturbations of the position of a particle levitated in vacuum. It combines feedback control of the supporting laser beam with adjustment of the beam shape and size in order to damp perturbations in both the vertical and horizontal directions by means of the vertical feedback damping apparatus.
