Long-Term Stability Analysis Towards <10-14 Level for a Highly Compact POP Rb Cell Atomic Clock

Autor: Almat, Nil, Gharavipour, Mohammadreza, Moreno, William, Gruet, Florian, Affolderbach, Christoph, Mileti, Gaetano

Long-term frequency instabilities in vapor-cell clocks mainly arise from fluctuations of the experimental and environmental parameters that are converted to clock frequency fluctuations via various physical processes. Here, we discuss the frequency s

Impact of microwave-field inhomogeneity in an alkali vapour cell using Ramsey double-resonance spectroscopy

Autor: Moreno, William, Pellaton, Matthieu, Affolderbach, Christoph, Almat, Nil, Gruet, Florian, Mileti, Gaetano

We numerically and experimentally evaluate the impact of the inhomogeneity of the microwave field in the cavity used to perform double-resonance (DR) Ramsey spectroscopy in a buffer gas alkali vapour cell. The Ramsey spectrum is numerically simulated

Characterization of Frequency-Doubled 1.5-μm Lasers for High-Performance Rb Clocks

Autor: Almat, Nil, Moreno, William, Pellaton, Matthieu, Gruet, Florian, Affolderbach, Christoph, Mileti, Gaetano

We report on the characterization of two fiber-coupled 1.5- μm diode lasers, frequency-doubled and stabilized to Rubidium (Rb) atomic resonances at 780 nm. Such laser systems are of interest in view of their implementation in Rb vaporcell atomic clo
