Evaluation of the blackbody radiation shift of an Yb optical lattice clock at KRISS

Myoung-Sun Heo, Huidong Kim, Dai-Hyuk Yu +2

As optical clocks are improved to reach the frequency uncertainty below the 10 level, the frequency shift due to the blackbody radiation (BBR) has been one of the major sys…

Absolute frequency measurement of the 171Yb optical lattice clock at KRISS using TAI for over a year

Huidong Kim, Myoung-Sun Heo, Chang Yong Park +2

We report a measurement of the absolute frequency of the 1S0-3P0 transition in the 171Yb optical lattice clock at KRISS (KRISS-Yb1) for 14 months, which was referenced to the SI se…

Advanced Satellite-based Frequency Transfer at the 10^{-16} Level

M. Fujieda, S-H. Yang, T. Gotoh +11

Advanced satellite-based frequency transfers by TWCP and IPPP have been performed between NICT and KRISS. We confirm that the disagreement between them is less than 1x10^{-16} at a…

Improved Absolute Frequency Measurement of the 171Yb Optical Lattice Clock at KRISS Relative to the SI Second

Huidong Kim, Myoung-Sun Heo, Won-Kyu Lee +4

We measured the absolute frequency of the - transition of Yb atoms confined in a one-dimensional optical lattice relative to the SI second. The determined f…

Drift-compensated Low-noise Frequency Synthesis Based on a cryoCSO for the KRISS-F1

Myoung-Sun Heo, Sang Eon Park, Won-Kyu Lee +9

In this paper we report on the implementation and stability analysis of a drift-compensated frequency synthesizer from a cryogenic sapphire oscillator (CSO) designed for a Cs/Rb at…

Cancellation of Collisional Frequency Shifts in Optical Lattice Clocks with Rabi Spectroscopy

Sangkyung Lee, Chang Yong Park, Won-Kyu Lee +1

We analyze both the s- and p-wave collision induced frequency shifts and propose a over- pulse scheme to cancel the shifts in optical lattice clocks interrogated by a Rabi pulse…
