Abstract

The invention relates to a transportation device. According to the invention, pulse polarization laser is divided into two beams of pulse laser through a polarization beam splitter; one beam of pulselaser is modulated into first photon orbital angular momentum spiral laser in a first spatial light modulator after being expanded; the other beam of pulse laser is modulated into a second photon orbital angular momentum spiral laser in a second spatial light modulator; the first photon orbital angular momentum spiral laser and the second photon orbital angular momentum spiral laser are combined in a polarization beam combiner to form photon orbital angular momentum spiral polarization pulse laser, the photon orbital angular momentum spiral polarization pulse laser rotates in a cavity of a heavy Fermion device to propel particles, so that the purpose of transporting medicines or microscopic particles is achieved, and the particles are transported in a non-direct contact manner.

Description

technical field [0001] The invention relates to the field of transporting microscopic particles, in particular to a transporting device. Background technique [0002] Photons are bosons, and bosons have the function of transmitting force, and the orbital angular momentum of photons can make microscopic particles rotate. However, there is currently no device that turns particles with photon orbital angular momentum while propulsively transporting them longitudinally. [0003] In the prior art, the tiny particle transport device is mainly composed of an input optical fiber and a section of fused-core capillary fiber. The fused-core capillary fiber is locally heated to form a thermal diffusion core, and the transmitted light transmitted in the core will pass through the hollow capillary. The inner surface forms an evanescent field. The tiny particles stored in the hollow capillary move along the inner surface of the hollow capillary to the direction of light wave transmission...
