By the photodissociation of PbI2 the high-lying metastable state of Pb 6p2 1D2 (21458 cm-1) can be populated. Stimulated emission, which depend on the population of the 6p2 1D2 metastable state, is observed. The populating process is discussed. Comparing the Raman scattering originating from 6p2 1D2 and 6p2 3P1, the population ratio of 1D2 to 3P1 is determined to be 1/30. Under the experimental conditions the variations of the ratio as function of the density of PbI2 and the intensity of the dissociation laser are small.
