An ultraviolet laser system for laser cooling and trapping of metastable magnesium
A. P. Kulosa, J. Friebe, M. P. Riedmann +8
We report on a reliable laser system for cooling magnesium atoms in the metastable 3P manifold. The three relevant transitions coupling the 3P to the 3D manifold are near 383 nm an…
Remote frequency measurement of the 1S0-3P1 transition in laser cooled Mg-24
J. Friebe, M. Riedmann, T. Wübbena +9
We perform Ramsey-Bordé spectroscopy on laser-cooled magnesium atoms in free fall to measure the 1S0 \rightarrow 3P1 intercombination transition frequency. The measured value of 65…
Long-distance remote comparison of ultrastable optical frequencies with 1e-15 instability in fractions of a second
Andre Pape, Osama Terra, Jan Friebe +8
We demonstrate a fully optical, long-distance remote comparison of independent ultrastable optical frequencies reaching a short term stability that is superior to any reported remo…
Potassium ground state scattering parameters and Born-Oppenheimer potentials from molecular spectroscopy
Stephan Falke, Horst Knoeckel, Jan Friebe +3
We present precision measurements with MHz uncertainty of the energy gap between asymptotic and well bound levels in the electronic ground state X of the $^{39…
Absolute frequency measurement of the magnesium intercombination transition
Jan Friebe, André Pape, Matthias Riedmann +9
We report on a frequency measurement of the clock transition of Mg on a thermal atomic beam. The intercombination transition has been referenced…
