Continuous cloud position spectroscopy using a magneto-optical trap
Benedikt Heizenreder, Ananya Sitaram, Sana Boughdachi +4
We demonstrate a continuous spectroscopy technique with frequency sensitivity well below the natural transition linewidth, while maintaining a locking range hundreds of times large…
A continuous-wave vacuum ultraviolet laser for the nuclear clock
Qi Xiao, Gleb Penyazkov, Xiangliang Li +14
The exceptionally low-energy isomeric transition in Th at around 148.4 nm offers a unique opportunity for coherent nuclear control and the realisation of a nuclear clock. R…
Quasi-continuous sub-K strontium source without a high-finesse cavity stabilized laser
Sana Boughdachi, Benedikt Heizenreder, Ananya Sitaram +8
We demonstrate a quasi-continuous sub-K strontium source achieved without the use of a high-finesse cavity-locked laser. Our frequency reference is based on a dispersion-optimiz…
Roadmap towards the redefinition of the second
N. Dimarcq, M. Gertsvolf, G. Mileti +34
This paper outlines the roadmap towards the redefinition of the second, which was recently updated by the CCTF Task Force created by the CCTF in 2020. The main achievements and the…
Absolute frequency measurements with a robust, transportable ^{40}Ca^{+} optical clock
Huaqing Zhang, Yao Huang, Baolin Zhang +9
We constructed a transportable 40Ca+ optical clock (with an estimated minimum systematic shift uncertainty of 1.3*10^(-17) and a stability of 5*10^(-15)/sqrt{tau} ) that can operat…
High-performance coherent population trapping atomic clock with direct-modulation distributed Bragg reflector laser
Peter Yun, Qinglin Li, Qiang Hao +7
The coherent population trapping (CPT) atomic clock is very promising for use in next-generation spaceborne applications owing to its compactness and high performance. In this pape…
