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

In this communication, we give an overview of the field of space atomic clocks and motivate the need for novel types of space atomic clocks, notably based on laser technology. We outline the development status of our pulsed laser-pumped Rb clock in v

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

We analyze the main effects that limit the frequency stability of a high-performance compact Rb vapor-cell atomic clock on medium- to long-term timescales up to one day, in view of identifying the fundamental clock stability limits. The clock is oper

We employ a three-level Bloch vector model to simulate Ramsey fringes of our Rb vapor-cell atomic clock. The residual inhomogeneity of the microwave magnetic field across the buffer-gas cell is a key ingredient for correctly modelling the behavior at

We employ a recently developed laser system, based on a low-noise telecom laser emitting around 1.56 μm, to evaluate its impact on the performance of an Rb vapor-cell clock in a continuous-wave double-resonance scheme. The achieved short-term clock

We report on the characterization of two fiber-coupled 1.5- $\mu \text{m}$ 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 vapor-cel

We report on a narrow-linewidth diode laser source emitting at 780 nm, based on frequency doubling from 1.56 μm, which is frequency stabilized on the D2 transition line of Rubidium (Rb). This compact laser source shows a frequency stability of 2·10
