Abstract

The fast development of CPT applications and the need of good magnetooptical sensors result in an increased interest in the Coherent Population Trapping (CPT) resonances and the processes that determine their shape. In this work the shape and width of the CPT resonances are investigated in two different paraffin-coated Rb vapor cells from point of view of understanding the processes influencing the shape of the resonances and building of miniature and sensitive detector. The dependence of the shape of the resonances on the laser power is measured. Narrow resonances on three hyperfine transitions of the D1 ⁸⁷Rb line are registered. For explanation of the bright structure in the resonance shapes at low laser powers analysis of the influence of different processes is made.
