An investigation is reported of coherent resonance in the degenerate two-level system of the (Fg=2→Fe=1) transition of the 87Rb D 1 line by means of a Hanle effect configuration. In a coherent population trapping experiment, a very narrow (~1-kHz) resonance superimposed upon a broader resonance (~100 kHz) was observed. The dependence of the width and the amplitude of the coherent resonance on the laser power density, on additional constant magnetic fields, on the laser frequency position along the fluorescence profile, and on Rb cells with different dimensions was investigated.
