Geometrical representation of the dressed atoms in the standing wave
Figure 1. Geometrical representation of the dressed atoms in the standing wave.
The resonance fluorescence emitted by two three-level atoms dressed in a strong laser field is studied. A stark dynamics shift based on photon statistics is discussed. The appearance of coherent Rabi oscillations (quantum beats) of the atoms located in the non-symmetric positions of the anti-nodes and the modification of the quantum correlations at the Stokes and anti-Stokes cooperative emission are described. For some positions of the atoms, we observed the violation of the Cauchy–Schwarz inequality, finding antibunching in the scattered light. We present a scheme to control the position of atoms dressed with the standing field via the resonance fluorescence.
