Dynamics of strongly coupled Yb atoms in a high-finesse cavity — •Dmitriy Sholokhov, Saran Shaju, and Jürgen Eschner — University of Saarland, Saarbrücken, Germany
We investigate the possibility of MOT trapping of 174Yb atoms using the 182 kHz narrow 1S0 - 3P1 (556 nm) transition, in order to generate lasing on the 1S0 - 3P0 clock transition (578 nm) using the virtual-state lasing mechanism described in [1]. While trapping with 556 nm light, the atomic cloud is considerably colder and denser as compared to the case of MOT trapping on the 28 MHz wide 1S0 - 1P1 line at 399 nm, which was used in [1]. We observe strong interaction between cavity and atoms in the scattering of frequency-shifted trap light into the cavity. The interaction, including the time-dependent atom number inside the cavity mode, leads to complex dynamics of the quantum system, which we characterize and analyze in this contribution.
