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…
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…
