Experimental results are presented about the transformation of the electromagnetically induced absorption resonance into the electromagnetically induced transparency one. The role of the depolarization of the excited state on the D_2 line of Cs atoms exposed to different confinements is discussed.

We present the first experimental observation of narrow dips in the fluorescence profiles of completely closed hyperfine transitions in Rb vapor at high atomic density, which is attributed to the depolarization of the excited state. Moreover, at low atomic density, a narrow peak on the top of the fluorescence profile is demonstrated, centered at the completely closed transition within the D_{2} line of Cs. Experiments are performed in thin (700 μm) alkali cell by single light beam spectroscopy. The cell is filled with Cs containing a small portion of Rb.
