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…
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…
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…
