We experimentally demonstrate a one-color two-photon transition from the$5\mathit{S}_{1/2}$ ground state to the $6\mathit{S}_{1/2}$ excited state inrubidium (Rb) vapor using a continuous wave laser at 993 nm. The Rb vaporcontains both isotopes ($^{85}$Rb and $^{87}$Rb) in their natural abundances.The electric dipole allowed transitions are characterized by varying the powerand polarization of the excitation laser. Since the optical setup is relativelysimple, and the energies of the allowed levels are impervious to stray magneticfields, this is an attractive choice for a frequency reference at 993 nm, withpossible applications in precision measurements and quantum informationprocessing.
