High-order optical nonlinearity at low light levels
Joel A. Greenberg, Daniel J. Gauthier
We observe a nonlinear optical process in a gas of cold atoms that simultaneously displays the largest reported fifth-order nonlinear susceptibility χ^(5) = 1.9x10^{-12} (m/V)^4 an…

Controllable ultra-broadband slow light in a warm Rubidium vapor
Rui Zhang, Joel A. Greenberg, Martin C. Fischer +1
We study ultra-broadband slow light in a warm Rubidium vapor cell. By working between the D1 and D2 transitions, we find a several-nm window centered at 788.4 nm in which the group…
