Autor: V I Yudin, A V Taichenachev, M Yu Basalaev, T Zanon-Willette, T E Mehlstäubler, R Boudot, J W Pollock, M Shuker, E A Donley, J Kitching

Publikováno v: New Journal of Physics, Vol 20, Iss 12, p 123016 (2018)

We have developed a universal method to form the reference signal for the stabilization of arbitrary atomic clocks based on Ramsey spectroscopy. Our approach uses an interrogation scheme of the atomic system with two different Ramsey periods and a sp

Inertial sensing with point-source atom interferometry for interferograms with less than one fringe

Autor: Elizabeth A. Donley, Yun-Jhih Chen, R. Boudot, Azure Hansen, John Kitching, Moshe Shuker

Publikováno v: Optical and Quantum Sensing and Precision Metrology.

Point source atom interferometry (PSI) is an atom-optical method that measures one axis of acceleration and two axes of rotation from atom-interferometric fringe images. The number of fringes in an image can be less than or larger than one, depending

Light-shift mitigation in a microcell-based atomic clock with Symmetric Auto-Balanced Ramsey spectroscopy

Autor: M. Abdel Hafiz, C. Carlé, N. Passilly, J. M. Danet, C. E. Calosso, R. Boudot

The mid-term fractional frequency stability of miniaturized atomic clocks can be limited by light-shift effects. In this Letter, we demonstrate the implementation of a symmetric Auto-Balanced Ramsey (SABR) interrogation sequence in a microcell-based

All-optical microwave feedback oscillator with atomic cell resonator

Autor: R. Boudot, M. Abdel Hafiz, M. Petersen, C. E. Calosso, E. Rubiola

Publikováno v: Applied Physics Letters. 120:044101

We report the demonstration of an all-optical self-sustained cell-based microwave feedback oscillator. In this scheme, a microwave resonance, optically induced in a buffer-gas filled vapor cell resonator through coherent population trapping (CPT), is
