We used a tunable cw dye laser to observe Doppler-free two-photon transitions to alkali-atom Rydberg levels. Real-time signals were obtained in an ionization cell of appropriate construction. The two-photon transition wavelengths to rubidium s levels were measured up to n = 50 with better than 1 x 10(-7) absolute accuracy and can be represented to within the experimental precision by a simple function of the principal quantum number, Other related transitions and future possibilities are considered.We used a tunable cw dye laser to observe Doppler-free two-photon transitions to alkali-atom Rydberg levels.

Fine Structure of the nD2 Series in Rubidium near the Ionization Limit

Kenneth C. Harvey, Boris Peter Stoicheff

Two-photon, Doppler-free spectroscopy with counter-propagating beams from a cw dye laser and a new type of thermionic detector have been used to study the $^{2}D_{\frac{3}{2}}$ and $^{2}D_{\frac{5}{2}}$ levels of Rb for Rydberg states up to $n=85$ , only 16 ${\mathrm{cm}}^{\ensuremath{-}1}$ from the ionization limit. It is shown that the fine-structure spacing varies as ${{n}_{\mathrm{eff}}}^{\ensuremath{-}3}$ for $n>\ensuremath{\sim}25$, and as a linear combination of ${{n}_{\mathrm{eff}}}^{\ensuremath{-}5}$ and ${{n}_{\mathrm{eff}}}^{\ensuremath{-}3}$ for $n<\ensuremath{\sim}25$.Two-photon, Doppler-free spectroscopy with counter-propagating beams from a cw dye laser and a new type of thermionic detector have been used to study the $^{2}D_{\frac{3}{2}}$ and $^{2}D_{\frac{5}{2}}$ levels of Rb for Rydberg states up to $n=85$, only 16 ${\mathrm{cm}}^{\ensuremath{-}1}$ from the ionization limit.
