The Miniaturized Integrating Sphere Cold Atom Clock based on Fiber Mirrors

SummaryDiffuse laser cooling provides a compact cold atom system for quantum precision measurement processes, especially for the integrating sphere cold atom clock. However, the laser cooling system of current integrating sphere cold atom clock is bulky and complex, which is not conductive to the miniaturization of cold atom clock. In order to make a less complex diffuse laser cooling system, we adopt the scheme to combine the fiber mirrors and the diffuse laser cooling technique. The incident laser beams are reflected by the fiber mirrors and teflon, and the atoms can be successfully cooled and detected in the miniaturized zone. The preparation of fiber mirrors and the realization of diffuse laser cooling system with a simple optical system can lay a solid foundation for further miniaturization of the overall system of integrating sphere cold atom clock in the future.
