Abstract

An experimental setup for cooling and trapping single 87Rb atom in a dipole micro-trap is developed. The minima of the trapping potential is 1.3 mK. The collisional blockade regime is gained, when only one single atom could be localized in a dipole micro-trap with probability P(1) ≈ 0.5. The average life time of an atom in the micro-trap is reached tens of seconds. The efficiency of quantum light matter interaction for an atom in free space in the regime of strong focusing is about 10%.
