Description:
A pulsed tunable dye laser was used for a high resolution experimental study of mercury fluorescence from the 6(3)P-1 state. The output of the dye laser was frequency doubled into the 253.7 nm region using a potassium pentaborate crystal. Exponential decays were separately observed for each of the five individual components of the hyperfine structure and the effects of the trapping of resonance radiation on the observed lifetime of the 6(3)P-1 state of mercury were investigated for each resolvable component. Within experimental error, the natural radiative lifetime of the 6(3)P-1 state was found to be independent of the hyperfine component irradiated and a value of 122 + or 2 nsec was obtained, consistent with results found by other methods.
