J. Koperski et al., OBSERVATION OF QUANTUM BEATS IN FORWARD SCATTERING AFTER STEPWISE EXCITATION - THE 3(2)P [--] 4(2)D SODIUM TRANSITION, Optics letters, 18(13), 1993, pp. 1086-1088
We describe quantum beats in forward scattering for the 3(2)P <-- -->
4(2)D transition in sodium. For the excitation of the 4(2)D3/2,5/2 sta
tes, the pulsed-stepwise method, through the 3P-2(1/2) or 3P-2(3/2) in
termediate level, was used. We observed changes in the quantum-beats p
attern that are due to the probe laser detuning, similar to these obse
rved previously for the sodium D2 line.
