Laser fractional frequency instability at with a room temperature optical reference cavity
Adam L. Parke, Eve Clulow, Wei Huang +8
Ultrastable lasers play a key role in optical frequency metrology, setting measurement speed and ultimately impacting both stability and accuracy of optical frequency standards. He…
Coordinated international comparisons between optical clocks connected via fiber and satellite links
Thomas Lindvall, Marco Pizzocaro, Rachel M. Godun +62
Optical clocks provide ultra-precise frequency references that are vital for international metrology as well as for tests of fundamental physics. To investigate the level of agreem…
300 μs optical cavity storage time and active RAM cancellation for laser frequency stabilisation
Adam L. Parke, Marco Schioppo
Frequency stabilisation of lasers to optical reference cavities is an established method to achieve state-of-the-art stability. The strengths of this method are the high discrimina…
International comparison of optical frequencies with transportable optical lattice clocks
International Clock, Oscillator Networking, Collaboration +37
Optical clocks have improved their frequency stability and estimated accuracy by more than two orders of magnitude over the best caesium microwave clocks that realise the SI second…
Yb optical clock with systematic uncertainty and absolute frequency measurements
Alexandra Tofful, Charles F. A. Baynham, E. Anne Curtis +9
A full evaluation of the uncertainty budget for the ytterbium ion optical clock at the National Physical Laboratory (NPL) was performed on the electric octupole (E3) $^2\mathrm{S}_…
Analysis of atomic-clock data to constrain variations of fundamental constants
Nathaniel Sherrill, Adam O. Parsons, Charles F. A. Baynham +13
We present a new framework to study the time variation of fundamental constants in a model-independent way. Model independence implies more free parameters than assumed in previous…
