Microfabricated alkali vapor cells with tunable He-Ne buffer gas mixture using reservoirs with laser-actuated break-seals
Clément Carlé, Andrei Mursa, Gabriel Faure +6
This letter reports on the generation of a tunable buffer gas mixture within microfabricated alkali vapor cells. We show that the combination of low-permeation windows with sequent…

Microcell CPT atomic clock using laser current-actuated power modulation with 10 range stability at 1 day
Carlos Manuel Rivera-Aguilar, Andrei Mursa, Clément Carlé +5
We present a coherent-population trapping (CPT) microcell atomic clock using symmetric auto-balanced Ramsey (SABR) spectroscopy. The pulsed SABR sequence is applied through direct…

On the reduction of gas permeation through the glass windows of micromachined vapor cells using AlO coatings
Clément Carlé, Andrei Mursa, Petri Karvinen +5
Stability and precision of atomic devices are closely tied to the quality and stability of the internal atmosphere of the atomic vapor cells on which they rely. Such atmosphere can…
