Abstract: The present disclosure discloses a vortex-pair beam based optical tweezer system, including a laser device (1), a collimating beam expanding system, a spatial light modulator (6), a confocal beam shrinking system, a sample table (12), and an observation unit arranged according to a light path.

The optical tweezer system can realize precise regulation, control, and positioning of two spherical particles at any positions in a plane, and any controllable rotation operation of a rod-shaped particle in the plane, which makes application objects of the optical tweezer system richer, and effectively solves the problem that the rod-shaped particle is difficult to be controlled by the existing optical tweezer system.

The materials in the stack may be alternated to provide tuning of the optical properties in the optical coating.

After passing through the collimating and beam-expanding system, the linearly-polarized Gaussian beam emitted by the laser is radiated to the spatial light modulator to be modulated in complex amplitude; the first-order diffraction beam of the emergent light generates an arbitrary-order alternating optical vortex array on the back focal plane of the first 2-f lens system, and an adjustable finite optical lattice with defects on the back focal plane of the second 2-f lens system. The topological charge value of each vortex and the spacing between vortices, in the generated arbitrary-order alternating optical vortex array, can be precisely controlled.
