Population Of Metastable Barium Associated With Conical Emission
By illuminating barium vapor with a cw broadband laser tuned to the blue of the $6s ; ^1S_0 ightarrow 6p ; ^1P_1$ transition we have observed a red--shifted conical emission. For the same laser detuning we measured a substantial population of the metastable barium levels $5d ; ^3D_J$. The spatial population distributions appear to be much broader than in the case of zero detuning. The implications of these results on the existing models for conical emission are discussed.
