Investigating the hyperfine systematic error and relative phase in low spin-polarization alkali FID magnetometers
D. P. Hewatt, M. Ellmeier, C. Kiehl +4
Alkali-metal optically-pumped magnetometers are prone to inaccuracies arising from the overlap of the average F = I + 1/2 and F = I - 1/2 ground-state Zeeman resonances. We employ…
Advanced light-shift compensation protocol in a continuous-wave microcell atomic clock
M. Abdel Hafiz, R. Vicarini, N. Passilly +7
Light-shifts are known to be an important limitation to the mid- and long-term fractional frequency stability of different types of atomic clocks. In this article, we demonstrate t…
Universal methods for suppressing the light shift in atomic clocks using power modulation
V. I. Yudin, M. Yu. Basalaev, A. V. Taichenachev +8
We show that the light shift in atomic clocks can be suppressed using time variation of the interrogation field intensity. By measuring the clock output at two intensity levels, er…
Optical pumping, decay rates and light shifts of cold-atom dark states
M. Shuker, J. W. Pollock, V. I. Yudin +2
Coherent dark states in atoms, created by simultaneous interaction of two coherent light fields with a 3-level system, are of prime importance in quantum state manipulation. They a…
Reduction of light shifts in Ramsey spectroscopy with a combined error signal
M. Shuker, J. W. Pollock, R. Boudot +4
Light-induced frequency shifts can be a key limiting contribution to the mid and long-term frequency instability in atomic clocks. In this letter, we demonstrate the experimental i…
Ramsey Spectroscopy with Displaced Frequency Jumps
M. Shuker, J. W. Pollock, R. Boudot +4
Sophisticated Ramsey-based interrogation protocols using composite laser pulse sequences have been recently proposed to provide next-generation high-precision atomic clocks with a…
