摘要：
Experimental investigation of the width, amplitude and shape of the Coherent Population Trapping (CPT) resonances for magnetic field measurements by means of a Hanle effect configuration (the single frequency CPT resonances) is presented. Different resonance width narrowing effects for increasing the sensitivity of the magnetometers are discussed. Numerical simulations based on density matrix formalism, which take into account the influence of the high rank polarization moments and the velocity distribution of the atoms have been performed for analysis of the shapes of the resonances.
