Problems solved by technology

However, affected by the diffraction limit of light, the characteristic scale of this periodic light field can only be limited to the linear range of the half-wavelength order, and the trapping of atoms can only be within this order of magnitude range, which is very important for the study of cold atoms. The interaction of the atom and the realization of deep cooling of atoms have brought some shortcomings

Embodiment Construction

[0026] Such as figure 1 As shown, the construction system of two-dimensional nano-localized light field for atom cooling includes incident laser 1, focusing and collimating lens assembly 2, polarizer 3, neutral atom magneto-optical trap optical adhesive 4, release laser 5, nanoparticle array 7 and substrate 8 . The principle of this system is to use the incident laser to irradiate the horizontally arranged nanoparticle array 7 to generate a locally enhanced near-field light field on the surface, which can effectively trap the loaded neutral cold atoms, thereby realizing the dual Dimensional nano localized light field.

[0027] The nanoparticle array 7 is placed on the substrate 8, so that the nanoparticle array 7 device is horizontally placed in the laser optical system. The nanoparticle array 7 is composed of spherical nanoparticles with a diameter of 10nm to 150nm, and the material is Ag or Au, prepared on the substrate 8 superior. The substrate 8 is made of SiO2 (glass),...

Abstract

The invention discloses a system for constructing an atom cooling-used two-dimensional nano local light field. The system is provided with a substrate for placing a nano particle array; an incident laser for emitting a laser beam to the nano particle array is arranged beside the substrate; a neutral atom magneto-optical trap optical adhesive is arranged above the nano particle array; and one side of the neutral atom magneto-optical trap optical adhesive is provided with a release laser for emitting a laser beam. Compared with the prior art, the system and the method have the following advantages that the local light field has a larger potential field gradient and a deeper optical trap depth, and atoms can be trapped more easily; the local light field has a smaller size, and the two-dimensional local light field of below 50nm can be realized easily; and the SiO2 (glass) is adopted to serve as a nano particle substrate, lighting can be reflected and transmitted, and the atom control mode is more diverse.

Description

technical field [0001] The invention relates to the fields of nanotechnology, cold atom physics and atomic optics, in particular to a system for realizing two-dimensional nanometer local light field for atom cooling. Background technique [0002] In recent years, the trapping of neutral cold atoms on solid surfaces has become one of the research hotspots in the fields of cold atom physics and atomic optics. It is of great significance in the research of quantum information, optical lattices and atomic chips. This technology has been gradually applied to the confinement and control of cold atoms and Bose-Einstein condensates (BEC), quantum transmission and tunneling effects, and the miniaturization and integration of quantum solid-state systems. [0003] In the traditional method, atom trapping is to use laser interference to form a gradient distribution of light field, form a periodic change of electric field potential energy, and trap atoms at the lowest point of potential ...
