Electromagnetically induced transparency (EIT) [1,2] has now been over the last decade
subject of many studies, both theoretical and experimental but numerical modeling is still
required to describe and analyse results of experiments carried out for complex systems
significantly differing from a basic three-level lambda set of atomic levels.
We present results obtained with a model developed for analysis of EIT properties of
a sample of hot rubidium atoms contained in a resonance cell filled with a buffer gas. The
model has been elaborated specifically for D1 transitions induced in 87 Rb (5 2 S 1//2 , F=1,2
→ 5 2 P 1//2 , F’=1). It involves 11 hyperfine states and accounts for most of the effects and
interactions that may influence EIT properties of the ensemble of Rb atoms.
