Evaluation of a Sr optical clock with a direct measurement of the blackbody radiation shift and determination of the clock frequency

M. Steinel, H. Shao, M. Filzinger +7

We report on an evaluation of an optical clock that uses the transition of a single Sr ion as the reference. In con…

Sub-kelvin temperature management in ion traps for optical clocks

T. Nordmann, A. Didier, M. Doležal +3

The uncertainty of the ac Stark shift due to thermal radiation represents a major contribution to the systematic uncertainty budget of state-of-the-art optical atomic clocks. In th…

Ultra-compact reference ULE cavity

Alexandre Didier, Jacques Millo, Baptiste Marechal +7

We present a first experimental characterization of our ultra-compact, ultra-stable laser. The heart of the apparatus is an original Fabry-Perot cavity with a 25 mm length and a py…

946-nm Nd:YAG digital-locked laser at in 1 s and transfer-locked to a cryogenic silicon cavity

A. Didier, S. Ignatovich, E. Benkler +2

We present a Nd:YAG ultra-stable laser system operating at 946 nm and demonstrate a fractional frequency instability of at 1 s by pre-stabilizing it to a 30 cm-…
