    • Bunching-induced optical nonlinearity and instability in cold atoms [Invited]. 

      Gauthier, Daniel J; Greenberg, JA; Schmittberger, BL (Opt Express, 2011-11-07)
      We report a new nonlinear optical process that occurs in a cloud of cold atoms at low-light-levels when the incident optical fields simultaneously polarize, cool, and spatially-organize the atoms. We observe an extremely ...
    • Controllable ultrabroadband slow light in a warm rubidium vapor 

      Fischer, MC; Gauthier, Daniel J; Greenberg, JA; Zhang, R (Journal of the Optical Society of America B: Optical Physics, 2011-01-01)
      We study ultrabroadband slow light in a warm rubidium vapor cell. By working between the D1 and D2 transitions, we find a several-nanometer window centered at 788:4nm in which the group index is highly uniform and the absorption ...
