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…
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…
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…
Absolute frequency measurement of 1S0 (F = 1/2) - 3P0 (F = 1/2) transition of 171Yb atoms in a one-dimensional optical lattice at KRISS
Chang Yong Park, Dai-Hyuk Yu, Won-Kyu Lee +9
We measured the absolute frequency of the optical clock transition 1S0 (F = 1/2) - 3P0 (F = 1/2) of 171Yb atoms confined in a one-dimensional optical lattice and it was determined…
Optical repumping of triplet -states enhances magneto-optical trapping of ytterbium atoms
Jun Woo Cho, Han-gyeol Lee, Sangkyung Lee +5
Radiative decay from the excited state to metastable and states is expected to limit attainable trapped atomic population in a magneto-optic trap of ytterbi…
