Abstract

We discuss the differences between two well-studied and related phenomena - coherent population trapping (CPT) and electromagnetically induced transparency (EIT). Many differences between the two - such as the effect of power in the beams, detuning of the beams from resonance, and the use of vapor cells filled with buffer gas - are demonstrated experimentally. The experiments are done using magnetic sublevels of the 1 -> 1 transition in the D-2 line of Rb-87.
