A chip-scale atomic beam clock
Gabriela D. Martinez, Chao Li, Alexander Staron +3
Atomic beams are a longstanding technology for atom-based sensors and clocks with widespread use in commercial frequency standards. Here, we report the demonstration a chip-scale m…
Electromagnetically induced transparency based Rydberg-atom sensor for quantum voltage measurements
Christopher L. Holloway, Nikunjkumar Prajapati, John Kitching +7
We investigate the Stark shift in Rydberg rubidium atoms through electromagnetically induced transparency for the measurement of direct current (dc) and 60~Hz alternating current (…
A simple imaging solution for chip-scale laser cooling
A. Bregazzi, P. F. Griffin, A. S. Arnold +6
We demonstrate a simple stacked scheme that enables absorption imaging through a hole in the surface of a grating magneto-optical trap (GMOT) chip, placed immediately below a micro…
High-performance, compact optical standard
Zachary L. Newman, Vincent Maurice, Connor Fredrick +6
We describe a high-performance, compact optical frequency standard based on a microfabricated Rb vapor cell and a low-noise, external cavity diode laser operating on the Rb two-pho…
Enhanced observation time of magneto-optical traps using micro-machined non-evaporable getter pumps
Rodolphe Boudot, James P. McGilligan, Kaitlin R. Moore +5
We show that micro-machined non-evaporable getter pumps (NEGs) can extend the time over which laser cooled atoms canbe produced in a magneto-optical trap (MOT), in the absence of o…
Robust inertial sensing with point-source atom interferometry for interferograms spanning a partial period
Yun-Jhih Chen, Azure Hansen, Moshe Shuker +3
Point source atom interferometry (PSI) uses the velocity distribution in a cold atom cloud to simultaneously measure one axis of acceleration and two axes of rotation from the phas…
Laser cooling in a chip-scale platform
J. P. McGilligan, K. R. Moore, A. Dellis +7
Chip-scale atomic devices built around micro-fabricated alkali vapor cells are at the forefront of compact metrology and atomic sensors. We demonstrate a micro-fabricated vapor cel…
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…
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…

J. W. Pollock, V. I. Yudin, M. Shuker +5
The off-resonant AC Stark shift for coherent population trapping (CPT) resonances probed with Ramsey spectroscopy is investigated experimentally and theoretically. Measurements wit…
Generalized auto-balanced Ramsey spectroscopy of clock transitions
V. I. Yudin, A. V. Taichenachev, M. Yu. Basalaev +5
When performing precision measurements, the quantity being measured is often perturbed by the measurement process itself. This includes precision frequency measurements for atomic…
