Improved frequency measurement of the $^{1} S_{0}$ - $^{3} P_{0}$ clock transition in $^{87}$ Sr using the Cs fountain clock at NMIJ as a transfer oscillator

Takehiko Tanabe, Daisuke Akamatsu, Takumi Kobayashi +10

We performed an absolute frequency measurement of the $^{1} S_{0}$ - $^{3} P_{0}$ transition in $^{87}$ Sr with a fractional uncertainty of $1.2 \times 1 0^{- 15}$ , which is less than one thi…

A compact iodine-laser operating at 531 nm with stability at the 10 $^{- 12}$ level and using a coin-sized laser module

Takumi Kobayashi, Daisuke Akamatsu, Kazumoto Hosaka +6

We demonstrate a compact iodine-stabilized laser operating at 531 nm using a coin-sized light source consisting of a 1062-nm distributed-feedback diode laser and a frequency-doubli…
