| Description | Journal: Journal of Physics: Conference Series A recent comparison between two trapped-ion$ ^{88}Sr^{+}$ optical clocks at the UK. National Physical Laboratory demonstrated agreement to 4 parts in $10^{17}$. One of the uncertainty contributions to the optical clock absolute frequency arises from the blackbody radiation shift which in turn depends on uncertainty in the knowledge of the differential polarisability between the two clocks states. Whilst a recent NRC measurement has determined the DC differential polarisability to high accuracy, there has been no experimental verification to date of the dynamic correction to the DC Stark shift. We report a measurement of the scalar AC Stark shift at 1064 nm with measurements planned at other wavelengths. Our preliminary result using a fibre laser at 1064 nm agrees with calculated values to within ~3%. |
