Abstract

Coherent population trapping (CPT) resonances in the degenerate two-level system of the F_g = 2 → F_e = 1) transition of the ⁸⁷Rb D₁ line were investigated in an uncoated vacuum cell by means of Hanle effect configuration. CPT signals with complex shape (narrow resonance approximately 2 mG superimposed on the wide one approximately 150 mG) were observed. The influence of weak transverse magnetic fields (0-1.2 G) on the amplitude and width of the two components was measured. The observed narrow resonances are interesting for application in high resolution spectroscopy and magnetometry.
