Dual-Mode Operation of an Optical Lattice Clock Using Strontium and Ytterbium Atoms

Daisuke Akamatsu, Takumi Kobayashi, Yusuke Hisai +4

We have developed an optical lattice clock that can operate in dual modes: a strontium (Sr) clock mode and an ytterbium (Yb) clock mode. Dual-mode operation of the Sr-Yb optical la…

A frequency-stabilized light source at 399 nm using an Yb hollow-cathode lamp

Takehiko Tanabe, Daisuke Akamatsu, Hajime Inaba +5

We demonstrate a diode laser system operating at 399 nm that is stabilized to the electric dipole transition in ytterbium (Yb) atoms in…
