Analysis of thermal radiation in ion traps for optical frequency standards
Miroslav Doležal, Petr Balling, Peter B R Nisbet-Jones +16
In many of the high-precision optical frequency standards with trapped atoms or ions that are under development to date, the AC Stark shift induced by thermal radiation leads to a…
Frequency comparison of Yb ion optical clocks at PTB and NPL via GPS PPP
J. Leute, N. Huntemann, B. Lipphardt +11
We used Precise Point Positioning, a well-established GPS carrier-phase frequency transfer method to perform a direct remote comparison of two optical frequency standards based on…
Broadband, unpolarized repumping and clearout light sources for Sr single-ion clocks
T. Fordell, T. Lindvall, P. Dubé +3
Future transportable optical clocks require compact and reliable light sources. Here, broadband, unpolarized repumper and state clearout sources for Sr+ single-ion optical clocks a…
8E-17 fractional laser frequency instability with a long room-temperature cavity
Sebastian Häfner, Stephan Falke, Christian Grebing +5
We present a laser system based on a 48 cm long optical glass resonator. The large size requires a sophisticated thermal control and optimized mounting design. A self balancing mou…
Radiocarbon Dioxide detection based on Cavity Ring-Down Spectroscopy and a Quantum Cascade Laser
Guillaume Genoud, Markku Vainio, Hilary Phillips +2
Monitoring of radiocarbon (C) in carbon dioxide is demonstrated using mid-infrared spectroscopy and a quantum cascade laser. The measurement is based on cavity ring-down spe…
Dark-state suppression and optimization of laser cooling and fluorescence in a trapped alkaline-earth-metal single ion
T. Lindvall, M. Merimaa, I. Tittonen +1
We study the formation and destabilization of dark states in a single trapped 88Sr+ ion caused by the cooling and repumping laser fields required for Doppler cooling and fluorescen…
