Towards a strontium optical frequency reference based on Ramsey-Bordé interferometry — •Ingmari C Tietje1, Oliver Fartmann1, Martin Jutisz1, Conrad L Zimmermann2, Vladimir Schkolnik1,2, and Markus Krutzik1,2 — 1Humboldt-Universität zu Berlin, Institut für Physik — 2Ferdinand-Braun-Institut GmbH, Leibniz-Institut für Höchstfrequenztechnik, Berlin
We present the status of our optical frequency reference based on Ramsey-Bordé interferometry using the 1S0 → 3P1 intercombination line in strontium. Next to the current state of the atom interferometer based on a thermal atomic beam, we will present details of our compact and high-flux atomic oven as well as the cavity-stabilised laser system at 689 nm.
