Atoms in strong light-fields: photon antibunching in single atom fluorescence

Claude N. Cohen-Tannoudji, Serge Reynaud

Abstract Some general remarks and suggestions concerning photon antibunching in single atom fluorescence are presented. The close connection between this antibunching effect and the ‘ reduction of the wave packet ’ due to the detection process is made explicit. It is pointed out that polarization effects could considerably change the shape of the signals. A dressed atom approach to these problems reveals analogies with quantum beats and suggests the use of frequency filters at the detection, selecting one component of the fluorescence spectrum and leading to new types of photon correlation signals.Abstract Some general remarks and suggestions concerning photon antibunching in single atom fluorescence are presented.

Collective atomic effects in resonance fluorescence

We suggest that the statistical properties of the scattered radiation in resonance-fluorescence experiments may be affected significantly by the existence of atomic correlations. The scattered light spectrum from two- and three-atom collective systems has been calculated and compared with the one-atom spectrum. The differences are quite significant for weak fields, but become less pronounced as the intensity of the driving field is increased. In addition, we have calculated the scattered intensity correlation function for collectively interacting systems, and found that its behavior is very different from that of the single-atom intensity correlation function, both for weak and strong incident fields. The implications of our findings for the observation of photon antibunching are also discussed.We suggest that the statistical properties of the scattered radiation in resonance-fluorescence experiments may be affected significantly by the existence of atomic correlations.

Fluorescence from a single atom interacting with antibunched light

Irina E. Lyublinskaya, Reeta Vyas

Statistical properties of fluorescent light from a single two-level atom driven by a beam of antibunched light are discussed in the weak field limit. Fields generated by realistic open systems with pumping and dissipation are chosen to be the models for antibunched light. As examples, we consider fields produced in intracavity second harmonic generation and in the homodyned degenerate parametric oscillator. These fields can be described in terms of real Gaussian random processes with coherent components. Analytical expressions for fluorescent light intensity and second order intensity correlation function in the steady state are derived. Effects of driving field correlations, detuning, and parameters characterizing the driving field on the statistics of scattered light are investigated. It is found that over a certain range of parameters characterizing the driving field the second order intensity correlation function may vanish at non-zero time. These and other interesting features will be discussed.Statistical properties of fluorescent light from a single two-level atom driven by a beam of antibunched light are discussed in the weak field limit.
