LEMAC: LTF-EPFL Miniature Atomic Clock : current status

Year: 2022

Type: conference-paper

Abstract: SummaryWe present the latest development of our in-house miniature atomic clock (LEMAC). The clock scheme is based on the continuous wave (CW) optical-microwave double resonance (DR) interrogation. Significant efforts have been put in a newly designed miniature microwave loop-gap resonator (LGR), laser locking scheme, and integrated Physics Package design. In its final state, our clock is expected to show a short-term stability performance of σy(τ)<1 × 10−11τ−1/2in terms of Allan deviation, for an insulated (magnetic and thermal) resonator volume <20 cm3.
