Frequency ratio measurement of 171Yb and 87Sr optical lattice clocks
Daisuke Akamatsu, Masami Yasuda, Hajime Inaba +4
The frequency ratio of the 1S0(F=1/2)-3P0(F=1/2) clock transition in 171Yb and the 1S0(F=9/2)-3P0(F=9/2) clock transition in 87Sr is measured by an optical-optical direct frequency…

Spectroscopy and frequency measurement of the Sr clock transition by laser linewidth transfer using an optical frequency comb
Daisuke Akamatsu, Hajime Inaba, Kazumoto Hosaka +5
We perform spectroscopic observations of the 698-nm clock transition in Sr confined in an optical lattice using a laser linewidth transfer technique. A narrow-linewidth lase…
