Rezumat

The possibility of realization of collective resonance fluorescence of extended systems of atoms in the strong travel and standing laser waves it is demonstrated. The influence of regular arrangement of the atoms in interaction with the laser pulls on the fluorescence intensity is analyzed. Taking in to account that such interference can be realize in two distant atomic ensembles we analyzed the collective interference phenomena between the fluorescent fields in the farther field detection region. These effects depend on the exchange integrals between systems of atoms through vacuum fluorescence field. The fluorescence spectrum of these atoms is found. About similar coherence interference experiment of spontaneous emission of light from two distant solid-state ensembles of atoms that are coherently excited by a short laser pulse it is reported in the papers [1,2]. For example, in paper [1] it is observed the entanglement between two distant atomic ensembles located in distinct apparatuses on different tables. Quantum interference in the detection of a photon emitted by one of the samples projects the otherwise independent ensembles into an entangled state with one joint excitation stored remotely in 105 atoms at each site. The experiment [2] relate about the ensembles of erbium ions doped into two LiNbO3 crystals with channel wave guides, which are placed in the two arms of a Mach - Zehnder interferometer. The light that is spontaneously emitted after the excitation pulse shows first-order interference. By a strong collective enhancement of the emission, the atoms behave as ideal two-level quantum systems and no which-path information is left in the atomic ensembles after emission of a photon. Influence of geometry of the sample on the coherent phenomena between two distant systems of atoms in this report is presented.
