【摘要】 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6p²³P₂与基态6p²³P。间的粒子数反分布。同时观察到基于6p²³P₂能级的受激共振辐射及受激喇曼散射。更多还原

【Abstract】 The population on 6p2 3P2 metastable state and 6p2 3P₀ 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.更多还原
