Abstract Atomic devices such as atomic clocks and optically-pumped magnetometers rely on the interrogation of atoms contained in a cell whose inner content has to meet high standards of purity and accuracy. Glass-blowing techniques and craftsmanship

We report on the mid-term stability progress of a table-top coherent population trapping (CPT) microcell atomic clock, previously limited by light-shift effects and variations of the cell's inner atmosphere. The light-shift contribution is now mitiga

International audience; CPT-based miniature atomic clocks are attractive ultra-compact, low-power and high-stability frequency references. However, their mid-long-term frequency stability suffers from several limitations including mainly light shifts
