Abstract

High-stability and compact clocks are in great demand for many applications, for example, such as global navigation satellite systems (GNSS), broadband communication networks and high-secret lines, smart electricity grids, etc. Many applications of the clocks require small size and weight (V < 50 cm3, m < 50 g), low power consumption (P << 1 W) and high long-term frequency stability (< 5×10-12 per a day). The most promising technology involves approach based on the coherent populations trapping (CPT) phenomenon, because it can combine all the features listed. Here we present the recent progress of development a version of CPT atomic clocks, which involves an antirelaxation-coated cell and the quadrature-signal method for the light shift cancellation.
