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…

Robust frequency stabilization and linewidth narrowing of a laser with large intermittent frequency jumps using an optical cavity and an atomic beam

Won-Kyu Lee, Chang Yong Park, Myoung-Sun Heo +2

An experimental method is developed for the robust frequency stabilization using a high-finesse cavity when the laser exhibits large intermittent frequency jumps. This is accomplis…

Studying fundamental limit of optical fiber links to level

Dan Xu, Won-kyu Lee, Fabio Stefani +3

We present an hybrid fiber link combining effective optical frequency transfer and evaluation of performances with a self-synchronized two-way comparison. It enables us to detect t…

Support-Area Dependence of Vibration-Insensitive Optical Cavities

Won-Kyu Lee, Sang Eon Park, Chang Yong Park +3

The vibration sensitivities of optical cavities depending on the support-area were investigated both numerically and experimentally. We performed the numerical simulation with two…

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…
