In frequency standards in which the atoms have a continuous interaction with the probe signal, local oscillator phase noise may limit medium term frequency stability. This spurious effect cannot be suppressed whenever there Is any truncation in the s

We calculate the contribution of the atomic shot noise in the detection of the laser-induced fluorescence signal emitted by atoms in a beam. We point out a filtering of such a contribution which is the consequence of the finite transit time of the at

The properties of optically pumped cesium-beam resonators showing a phase difference, /spl Phi/, of /spl pi/ between the two oscillatory fields are analyzed. They are compared with those occurring with /spl Phi/=0, when the interrogation signal is sl

Different stochastic models of a stable frequency and time sources showing white phase noise, white frequency noise, and random walk of frequency noise are considered. A continuous time model of phase fluctuations is associated with the power law mod

Recent advances in atomic physics will make it possible to reach frequency stabilities in the range of 10/sup -14/-10/sup 15/ tau /sup -1/2/ for passive atomic frequency standards. However, it is recognized that the frequency noise in the interrogati

When observed in a cesium beam frequency standard, the hyperfine transition frequency of the atoms differs slightly from the invariant transition frequency of the unperturbed atoms at rest. The various physical and technical origins of the frequency
