Laser Frequency Stabilization Using Light Shift in Compact Atomic Clocks
Claudio E. Calosso, Michele Gozzelino, Filippo Levi +1
This paper describes the Light-Shift Laser-Lock (LSLL) technique, a novel method intended for compact atomic clocks that greatly simplifies the laser setup by stabilizing the pumpi…
A pulsed optically pumped Rb clock with a frequency stability below 10-15
Michele Gozzelino, Salvatore Micalizio, Claudio E. Calosso +4
We present the frequency stability performances of a vapor cell Rb clock based on the pulsed optically pumping (POP) technique. The clock has been developed in the frame of a colla…
Frequency noise characterization of diode lasers for vapor cell clocks applications
Gaspare Antona, Michele Gozzelino, Salvatore Micalizio +3
The knowledge of the frequency noise spectrum of a diode laser is of interest in several high resolution experiments. Specifically, in laser-pumped vapor cell clocks, it is well es…
Cold Atoms in Space: Community Workshop Summary and Proposed Road-Map
Ivan Alonso, Cristiano Alpigiani, Brett Altschul +246
We summarize the discussions at a virtual Community Workshop on Cold Atoms in Space concerning the status of cold atom technologies, the prospective scientific and societal opportu…
Loaded microwave cavity for compact vapor-cell clocks
Michele Gozzelino, Salvatore Micalizio, Claudio E. Calosso +3
Vapor-cell devices based on microwave interrogation provide a stable frequency reference with a compact and robust setup. Further miniaturization must focus on optimizing the physi…
Reducing cavity-pulling shift in Ramsey-operated compact clocks
Michele Gozzelino, Salvatore Micalizio, Filippo Levi +2
We describe a method to stabilize the amplitude of the interrogating microwave field in compact atomic clocks working in a Ramsey approach. In this technique, we take advantage of…
Phase-shift in vapor cell and compact cold-atom frequency standards
Aldo Godone, Salvatore Micalizio
We report on a theoretical analysis of the phase-shift in compact atomic clocks working either with cold or thermal atoms. It is well known that in a microwave cavity with electrom…
High-performance coherent population trapping clock with polarization modulation
Peter Yun, François Tricot, Claudio Eligio Calosso +5
We demonstrate a vapor cell atomic clock prototype based on continuous-wave (CW) interrogation and double-modulation coherent population trapping (DM-CPT) technique. The DM-CPT tec…
Realization of a twin beam source based on four-wave mixing in Cesium
G. Adenier, D. Calonico, S. Micalizio +3
Four-wave mixing (4WM) is a known source of intense non-classical twin beams. It can be generated when an intense laser beam (the pump) and a weak laser beam (the seed) overlap in…
Avoiding Aliasing in Allan Variance: an Application to Fiber Link Data Analysis
Claudio E. Calosso, Cecilia Clivati, Salvatore Micalizio
Optical fiber links are known as the most performing tools to transfer ultrastable frequency reference signals. However, these signals are affected by phase noise up to bandwidths…
Evaluating Optical Fiber Links with Data Filtering and Allan Deviation
Claudio Eligio Calosso, Cecilia Clivati, Salvatore Micalizio
In this paper we propose a simple method to reject the high-frequency noise in the evaluation of statistical uncertainty of coherent optical fiber links. Specifically, we propose a…
Metrological characterization of the pulsed Rb clock with optical detection
Salvatore Micalizio, Claudio Calosso, Aldo Godone +1
We report on the implementation and the metrological characterization of a vapor-cell Rb frequency standard working in pulsed regime. The three main parts that compose the clock, p…
Black Body Radiation Shift of the 133Cs Hyperfine Transition Frequency
S. Micalizio, A. Godone, D. Calonico +2
We report the theoretical evaluations of the static scalar polarizability of the 133Cs ground state and of the black body radiation shift induced on the transition frequency betwee…
Measurement of the Blackbody Radiation Shift of the 133Cs Hyperfine Transition in an Atomic Fountain
F. Levi, D. Calonico, L. Lorini +2
We used a Cs atomic fountain frequency standard to measure the Stark shift on the ground state hyperfine transiton frequency in cesium (9.2 GHz) due to the electric field generated…
