In the strong-coupling regime, a single atom placed in a high-finesse cavity can substantially alter the transmission of the resonator. This effect allows for continuous observation of the atom inside the cavity. The dipole force of the near-resonant probe field has a significant influence on the motion of a cold atom and can be used to catch and trap a single atom in the cavity . However, the storage time is limited due to spontaneous scattering of photons.
We now combine the near-resonant light field used to observe the atom with a far-detuned light mode of the cavity to trap the atom . This trapping scheme strongly extends the storage time of a single atom, permitting us to continuously observe the oscillation of an individual atom in both axial and radial directions.
