| (a) Schematic diagram of the experimental setup. APD: avalanche photodiode working in the photon-counting mode; IF: 852-nm interference filter; PM fiber: polarization-maintaining fiber. (b) Transferring single atom between the MOT and the optical microscopic tweezer. Step fluorescence signals are obtained from the trapped atoms, the background light in tweezer ( C OT) and MOT ( C 0), single-atom events ( C 1) and two atoms ( C 2). |
