Title:
LASER TRANSMISSION DEVICE AND ION TRAP SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/040615
Kind Code:
A1
Abstract:
The present application discloses a laser transmission device and an ion trap system. The laser transmission device is applied to an ion trap system, and comprises a spatial spot-size converter and an array of diffractive elements. The spatial spot-size converter and the array of diffractive elements are located in different planes in space. The spatial spot-size converter is used for irradiating multiple laser beams to the array of diffractive elements. The array of diffractive elements is used for independently irradiating the multiple laser beams to corresponding ions, respectively. After passing through the diffractive elements, a column of laser beams emitted along a direction perpendicular to an ion chain are not parallel to each other. In this solution, since the array of diffractive elements is not coplanar with the spatial spot-size converter, the arrangement mode and number of the diffractive elements are not limited by the spatial spot-size converter, and the array of diffractive elements is easy to expand; moreover, the non-coplanar design eliminates the need for optical fibers to be directly coupled to a chip, thereby avoiding the limitation of chip size on the number of optical fibers; and the array arrangement of the diffractive elements is beneficial to increasing the numerical apertures of the diffractive elements, increasing the focusing capability of the diffractive elements, and outputting high-quality focused small light spots, thereby reducing crosstalk.
