PbCl2分子的光解离

用YAG激光的四次谐波光解离PbCl₂分子。实验确认了这种光解过程是双光子过程。通过对激光诱导荧光的测量,发现这一光解过程造成了Pb原子的亚稳态6p^{2 3}P₂与基态6p^{2 3}P。间的粒子数反分布。同时观察到基于6p^{2 3}P₂能级的受激共振辐射及受激喇曼散射。 关键词：

PHOTODISSOCIATION OF PbCl2

The population on 6p^{2 3}P₂ metastable state and 6p^{2 3}P₀ ground state of Pb atoms are de-monstrated, which are originated from dissociating PbCl₂ by the fourth harmonic of YAG lasers. The population ratio of ³P₂ to ³P₀ is measured in terms of laser-induced fluorescence. The results indicate that the dissociation of PbCl₂ is a two photon process and the population inversion between ³P₂ and ³P₀ exists. The stimulated Raman radiation based on the population of ³P₂ metastable state is observed. The possible way of dissociation is studied.
