Large Momentum Transfer Clock Atom Interferometry on the 689 nm Intercombination Line of Strontium

Journal Article · · Physical Review Letters
We report the first realization of large momentum transfer (LMT) clock atom interferometry. Using single-photon interactions on the strontium $$^1S_{0^–}^3P_1$$ transition, we demonstrate Mach-Zehnder interferometers with state-of-the-art momentum separation of up to 141 $$\textit{ℏk}$$ and gradiometers of up to 81 $$\textit{ℏk}$$. Furthermore, we circumvent excited state decay limitations and extend the gradiometer duration to 50 times the excited state lifetime. Because of the broad velocity acceptance of the interferometry pulses, all experiments are performed with laser-cooled atoms at a temperature of 3 μK. This work has applications in high-precision inertial sensing and paves the way for LMT-enhanced clock atom interferometry on even narrower transitions, a key ingredient in proposals for gravitational wave detection and dark matter searches.
