Rb vapor

hot rubidium vapor. This is made possible by long lived twophoton coherences at frequencies that allow propagation under phasematching conditions. Depending on the polarization of the pump lasers, upconversion can be enhanced or almost completely suppressed. Alkali metal vapors are versatile tools for spectroscopy and nonlinear optics in atomic
