Three-Photon Transfer and Inelastic Collisions in 84Sr

Poster 16
Presenter: Junyu He (University of Amsterdam)
Authors: Davide Natale (University of Amsterdam), Benjamin Pasquiou (Université Sorbonne Paris Nord), Florian Schreck (University of Amsterdam)

This work describes how we achieve a coherent three-photon transfer between the internal states 1S0 and 3P0 of 84Sr and how two-body inelastic collisions occur between these states. Despite challenges in achieving a complete transfer, we highlight the potential uses for outcoupling atoms into a continuous atom laser beam and for quantum computing. Our method allows us to prepare a high phase-space density cloud of 3P0 atoms. This was previously difficult due to an unfavorable elastic-to-inelastic ratio, making traditional evaporative cooling impractical. Additionally, we pioneer the measurement of inelastic collisional loss rates for 3P0 atoms in 84Sr. Our method opens up new possibilities for realizing quantum degenerate samples in the metastable 3P0 and 3P2 states of alkaline-earth-like atoms.
