In this paper, we describe an experiment for two-photon excitation in laser-cooled 87Rb using an optical nanofiber. A brief description of the multilevel atom scheme is followed by experimental results on two-photon absorption and observation of Autler-Townes splitting in cold atoms. These experiments use powers several orders of magnitude lower than those used in free space experiments.
