| Abstract: | The technique of two-photon laser spectroscopy without Doppler broadening is applied to atomic rubidium vapor. The hyperfine splitting and isotope shifts of several highly excited states are measured. We demonstrate the suitability of a tunable laser source oscillating simultaneously in many longitudinal modes for two-photon spectroscopy. |
