Abstract

We have developed a simple technique for controlling the number of a few 85Rb atoms in a magneto-optical trap based on a magnetic-field- gradient feedback mechanism for suppressing stochastic loading and loss events. The occupation probability of single atom was observed to be as high as 93.5%. Two and three atoms were also trapped with high occupation probabilities. Second order correlation functions of resonance fluorescence for one, two and three atoms were measured, showing strong photon antibunching. The degree of antibunching was reduced as the atom number was increased.
