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…

Preliminary characterization of a surface electrode Paul trap for frequency metrology
Josipa Madunic, Lucas Groult, Bachir Achi +7
We are developing a single-ion optical clock based on a surface-electrode (SE) trap that we will operate with Yb ions on the electric quadrupole transition at 435.5 nm.…

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…
