Abstract
An optically trapped atom transfer tweezer includes an optical modulator which modulates incident light and generates a first hologram; a first lens which images the first hologram on an intermediate image plane and generates a first holographic image having any potential shape; a second lens which re-images the first holographic image on an entrance pupil of a third lens; the third lens which re-images a second hologram generated by the re-imaging of the second lens on a plane where an optically trapped atom array exists; a photographing device which captures optically trapped cold atoms from a second holographic image generated on the plane where an optically trapped atom array exists; and a controller which controls the optical modulator to adjust the second holographic image on the basis of the optically trapped atom image captured by the photographing device such that the optically trapped atom array is transferred to any spatial position.
