Photoionization Raman Spectroscopy
Beterov I.M., Fateev N.V., Chebotarev V.P.
Experiments are reported on the photoionization detection of stimulated Raman scattering by electronic transitions of sodium in an atomic beam. There is a dip in the signal corresponding to the nonresonant two-photon ionization of sodium by electromagnetic radiation at/tj = 284.5 nm andA2 = 1.06μτη. The dip is due to a Raman resonance at the forbidden 3s~4s transition.
