J. Chorazy et al., INVESTIGATION OF RESONANCE RADIATION TRAPPING FOR OPTICALLY SATURATED3(2)S(1 2)-]3(2)P(1/2) TRANSITION IN SODIUM VAPOR/, Optics communications, 125(1-3), 1996, pp. 65-69
Resonance fluorescence affected by a radiation trapping has been obser
ved in two different cases: strong and weak excitation of the 3(2)P(1/
2) sodium level. The experiment confirmed a previously predicted effec
t, that in an optically bleached medium the fluorescence signal can de
crease faster than the natural decay. A good agreement between numeric
al calculations and experimental data was found.
