Instabilities of the continuous superradiant laser
Bruno Laburthe-Tolra, Martin Robert-de-Saint-Vincent, Benjamin Pasquiou
We investigate the intensity stability of the superradiant laser. Our study focuses on the architecture where a continuous beam of atoms in an electronically excited state crosses…

Coherent control over the high-dimensional space of the nuclear spin of alkaline-earth atoms
Husain Ahmed, Andrea Litvinov, Pauline Guesdon +5
We demonstrate coherent manipulation of the nuclear degrees of freedom of ultracold ground-state strontium 87 atoms, thus providing a toolkit for fully exploiting the corresponding…

Coherent Three-Photon Excitation of the Strontium Clock Transition
Junyu He, Benjamin Pasquiou, Rodrigo Gonzalez Escudero +3
We demonstrate coherent three-photon excitation of the strontium clock transition with a contrast of 51(12)% using a Bose-Einstein condensate. We follow it up with a demonstration…
