Abstract We report the results of a study of two-color laser excitation, ω1 + ω2, in dense sodium vapor where ω1 was tuned in the vicinity of the 3P fine structure doublet and ω2 was tuned to highernl states. Resonant excitation by ω2 of higherns andnd states from one member of the 3P doublet when ω1 is tuned near the other is attributed to collisional excitation transfer. Anomalous dipole forbiddenp-p transitions are observed when ω2 is tuned to highnP states (≥20) and are believed to be DC electric field induced. Sample spectra for the processes considered are calculated and compared with experiment.
