Collective atom-cavity interactions in a high-finesse dual-wavelength cavity
Abstract/Contents
- Abstract
- We developed a high-finesse single-wavelength cavity with a large collective cooperativity to achieve pseudospin squeezing and study collective atom-cavity interactions. We observed collective normal mode splitting, providing evidence for a large collective cooperativity that can result in better spin-squeezing. We observed ~13dB large anti-spin-squeezing but little spin-squeezing because of the inhomogeneous atom-cavity coupling, limiting the atomic coherence. In order to achieve identically coupled atoms to a cavity mode, we developed a high-finesse dual-wavelength cavity with a 1560nm cavity lattice and a 780nm cavity probe. Optically trapped atoms in the lattice are in-phase with the cavity probe at the cavity center, and we obtained spatially identical atom-cavity coupling. We studied macroscopic self-trapping behavior of two hyperfine levels experimentally and theoretically, and in-phase atom registration in the dual-wavelength cavity enables us to treat the trapped atoms as one macroscopic ensemble of atoms. At the mid-point of a full Rabi oscillation, the collective atom-cavity interaction interrupts the coherent evolution of the macroscopic ensemble of atoms. We demonstrated a free-running Raman laser in our cavity system using 87Rb atoms as the gain medium, which has atypical lasing threshold behavior and tunable gain properties. The intermode laser linewidth is as low as 80Hz.
