A High-frequency Geodetic VLBI Experiment for Optical Clock Comparison
Monia Negusini, Myoung-Sun Heo, Cecilia Clivati +40
An intercontinental metrological clock comparison between Italy and the Republic of Korea was performed by means of geodetic K-band VLBI observations. The comparison involved the h…
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…
Absolute frequency measurement of a Yb optical clock at the limit of the Cs fountain
Irene Goti, Stefano Condio, Cecilia Clivati +6
We present the new absolute frequency measurement of ytterbium (171Yb) obtained at INRiM with the optical lattice clock IT-Yb1 against the cryogenic caesium (133Cs) fountain IT-CsF…
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…
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…
