Transformation of the coherent population trapping resonance into enhanced fluorescence in a paraffin coated Rb vacuum cell

Peculiarities of the coherent population trapping resonance in the fluorescence obtained in a coated87Rb cell in the presence of transverse magnetic field: theory and experiment

“…The atomic system was modeled by a set of sub-ensembles interacting with different light fields. We have also investigated the CPT resonance dependence on the laser power and the experimental geometry in a coated cell [14,15]. In [14] only the narrow component of the CPT resonance was registered (range of MF scan ±mG).…”

“…We have also investigated the CPT resonance dependence on the laser power and the experimental geometry in a coated cell [14,15]. In [14] only the narrow component of the CPT resonance was registered (range of MF scan ±mG). It was obtained that the sign of resonance changes from bright to dark, depending on the laser power and experimental geometry.…”
