我们报告了我们认为是首次观察到的激光诱导荧光带，该荧光带是通过使用“泵浦探针”方法从 Hg 3 准分子的低位态吸收而激发的。对荧光强度与“泵浦”和“探测”激光脉冲之间的时间间隔的关系的研究为激光激发的汞蒸气中同时存在 Hg 3 和 Hg 2 分子提供了明确的证据。荧光可能是由于三聚体发射或三聚体状态解离后的二聚体发射。
We report what we believe to be the first observation of a laser-induced fluorescence band, excited by absorption from a low-lying state of the Hg 3 excimer using a ‘‘pump-and-probe’’method. A study of the fluorescence intensity as a function of the time separation between the ‘‘pump’’and ‘‘probe’’laser pulses provides clear evidence for the presence of both Hg 3 and Hg 2 molecules in the laser-excited mercury vapor. The fluorescence may be due to trimer emission or to dimer emission following dissociation of a trimer state.
