Cavity QED systems are promising candidates for the implementation of Quantum Information protocols. Some of these systems rely on the coherent coupling of single or multiple atoms with an optical field inside a resonator. It is essential to obtain precise control on the number of atoms and their relative position inside the cavity, for instance for specific entanglement generation protocols [1].

In this work, we present an experimental technique to create predefined patterns of a few atoms inside a fiber Fabry-Perot resonator, in real-time. First, several 87Rb atoms are trapped in a 3D optical lattice inside the fiber cavity. Then, using an EMCCD camera, a fluorescence image of the atoms is acquired in situ, and next the atoms in undesired lattice sites are removed using a focused push-out beam, directed by a 2D acousto-optic deflector.
