Abstract
This research presents the theoretical demonstration of a grating chip that can facilitate a miniature dipole trap system for rubidium atoms. The innovative chip design is expected to form both a magneto-optical trap and a dipole trap with a single laser. The paper further examines the dependence of the chip’s focusing properties and diffraction efficiency on its structural parameters. Findings confirm the proposed design’s ability to effectively trap atoms. The research also proposes a compact vacuum chamber design compatible with the grating chip. This design incorporates a non-evaporable getter and dispenser, utilizing materials with minimal outgassing and helium permeation rates.
