Cavity Nonlinear Optics at Low Photon Numbers from Collective Atomic Motion
Cavity Nonlinear Optics at Low Photon Numbers from Collective Atomic Motion
We report on Kerr nonlinearity and dispersive optical bistability of a Fabry-Perot optical resonator due to the displacement of ultracold atoms trapped within. In the driven resonator, such collective motion is induced by optical forces acting upon up to 10(5) 87Rb atoms prepared in the lowest band of a one-dimensional …
