Production of Miniature Glass Cells with Rubidium for Chip Scale Atomic Clock

The main advantage of chip scale atomic clock (e.g., Knappe (2008)) (CSAC) over quartz-oscillators is the higher long-term stability. It is provided by non-aging resonance of unperturbed atoms. However it is not a simple task to suppress all possible perturbations. Hence, metrological properties of resonance depend on the way in which ensemble of atoms is localized in space and protected. The paper describes a technology of small all-glass Rb cells production. The sealing of cells is made with radiation of a СО2 lasers. The cells will be utilized in Rb CSAC based on the phenomenon of coherent population trapping (CPT). (Pat. No RU 2014101361)
