摘要：

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. (C) 2001 Elsevier Science B.V. All rights reserved.
