Atom-based stabilization for laser-pumped atomic clocks



Vladislav Gerginov, V Shah, Svenja A. Knappe, Leo W. Hollberg, John E. Kitching


We describe a novel technique for stabilizing frequency shifts in laser-interrogated vapor-cell atomic clocks. The method suppresses frequency shifts due to changes in the laser frequency, intensity and modulation index as well as atomic vapor density. The clock operating parameters are monitored using the atoms themselves, rather than using conventional schemes for laser frequency and cell temperature control. The experiment is realized using a chip-scale atomic clock (CSAC). The novel atom-based stabilization approach results in a simpler setup and improved long-term performance of the atomic clock.
