Frequency stability of a wavelength meter and applications to laser frequency stabilization [PDF]
Applied Optics, 2015 Interferometric wavelength meters have attained frequency resolutions down to the MHz range. In particular, Fizeau interferometers, which have no moving parts, are becoming a popular tool for laser characterization and stabilization. In this article, we characterize such a wavelength meter using an ultra-stable laser in terms of relative frequency ...

Characterization of frequency stability in precision frequency sources [PDF]
Proceedings of the IEEE, 1991 The authors present a short review of the progress that has occurred during years 1955-91 in both the theoretical and practical characterization of frequency stability of precision frequency sources. The emphasis is on the evolution of ideas and concepts for the characterization of random noise processes in such standards in the time domain and the ...

Frequency stability in resonator-stabilized oscillators [PDF]
IEEE Transactions on Circuits and Systems, 1990 A simplified stability analysis of resonator-stabilized oscillators is carried out by using the describing function approach. On this basis a criterion for the evaluation and optimization of the frequency stabilization introduction in an oscillator by a resonating element with a large quality factor is proposed. In particular, a frequency-stabilization
