Abstract

We examine the role of nearby hyper-fine levels in a three-level transparency driven system in which a slow group velocity of light propagation is anticipated. In addition to accounting for the significant (>80%) probe field loss, our theory can accurately model the significant (near 30%) pulse broadening found in two recent experiments. Other excitation schemes for reducing the absorption from nearby levels are discussed.
