Abstract
Dilute rubidium gases at submicrokelvin temperatures offer the possibility of exceptionally small and negative group velocities. We devise an experime ntal scheme in which nearly dispersionless and highly superluminal pulse pr opagation at optical frequencies can be observed. Comparisons with other sc hemes and potential applications are briefly discussed.
