The quantum jump statistics in the fluorescence intensity from two three-level atoms is studied. A rate-equation description valid for strong driving fields is derived, and a partial analysis of quantum jump statistics which goes beyond the strong-excitation limit is presented. As the main result, it is shown that collective effects, such as unusual intensity levels and double quantum jumps, can occur in two-atom systems. However, their observation requires that the atoms be localized within a wavelength of light.>

We have studied cooperative effects on quantum jumps in two-atom systems. These atoms have either two or three states and are driven by a field of arbitrary intensity and bandwidth. We find that, in two two-state atoms at a small separation distance, quantum jumps appear, while the jump rates in two three-state atoms are modified by the collective interactions. Explicit expressions for jump rates are given in various explicit cases.
