| Résumé |
The authors present the realisation and characterisation of an
additively manufactured (AM) microwave resonator cavity for
double-resonance (DR) vapour-cell atomic clocks. The design of the
compact microwave cavity is based on the loop-gap resonator
approach, previously demonstrated for conventionally-machined
aluminium components. In the present study, the resonator is
fabricated by AM using a metal-coated polymer. A resonance
frequency at the desired 6.835 GHz rubidium atomic frequency is
obtained. When employed in an atomic clock setup, the AM cavity
enables a DR signal of <;500 Hz linewidth and of nearly 20%
contrast, thus fulfilling the stringent requirements for DR atomic
clocks. A clock short-term stability of 1 × 10 -12 τ -1/2 is
demonstrated, comparable to state-of-the-art clock performances. |
