IEEE transactions on microwave theory and techniques, 2023
To miniaturize the double-resonance (DR) rubidium (Rb) vapor-cell atomic clocks, a new type of micro-loop-gap microwave resonator ( $\mu $ -LGR) is proposed for TE011-like mode where the magnetic field inside the cavity is homogeneous and oriented along ...

Microwave interrogation cavity for the rubidium space cold atom clock
Chinese Physics B, 2016The performance of space cold atom clocks (SCACs) should be improved thanks to the microgravity environment in space. The microwave interrogation cavity is a key element in a SCAC. In this paper, we develop a microwave interrogation cavity especially for the rubidium SCAC.

A Compact Laser System for the Pulsed Optically Pumped Rubidium Cell Atomic Clock
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2022We describe the design and implementation of a compact laser system for the pulsed optically pumped (POP) rubidium (Rb) cell atomic clock. The laser system includes packaged optics for sub-Doppler absorption, acousto-optic modulation and light beam expansion, and dedicated electronics for laser diode reliable single-mode operation and laser frequency ...

100-ns-level timing holdover after 12 years for rubidium atomic fountains
Physical Review AppliedWhile atomic frequency standards are improving at a staggering pace, the timing community has relied on the same continuously running atomic clocks for decades: commercial cesium beams and hydrogen masers.
