Broadband and flat-baseline dual-comb cavity mode dispersion spectroscopy using fiber-based frequency combs
Sho Okubo, Ken Kashiwagi, Koji Hashiguchi +1
We demonstrate broadband dual-comb cavity mode dispersion spectroscopy using mode-locked erbium-fiber frequency combs and a length-tunable optical cavity. The flat baseline and low…
Optical sound pressure measurement using Fabry-Pérot cavity for primary acoustic standards
Koto Hirano, Wataru Kokuyama, Hajime Inaba +5
Optical sound pressure measurement is a promising technology to establish primary acoustic standards without reliance on specific types of microphones. We developed a precision opt…
Improved absolute frequency measurement of Yb at NMIJ with uncertainty below
Takumi Kobayashi, Akiko Nishiyama, Kazumoto Hosaka +6
We report improved absolute frequency measurement of the SP transition of Yb at National Metrology Institute of Japan (NMIJ) by comparing the $^{171}…
Measurement of transition frequencies and hyperfine constants of molecular iodine at 520.2 nm
Akiko Nishiyama, Sho Okubo, Takumi Kobayashi +2
We measured the transition frequencies of the hyperfine components in the four lines (P(34) 39-0, R(36) 39-0, P(33) 39-0, and R(35) 39-0) of the B-X transitions of molecular iodine…
