【摘要】 本文报道和分析了以He和Ar为缓冲气体、在XeF351nm及N₂337nm紫外激光泵浦下,得到锂蒸气在500～600nm波段新的激光感生荧光谱,初步探讨了产生这个新谱区的上、下能级。给出了锂蒸气中可能存在的动力学过程。还报道了用XeCl308nm紫外激光激励香豆素102染料产生的～474nm激光线泵浦锂蒸气所得到的数条超辐射线。更多还原

【Abstract】 A new laser-induced fluorescence spectrum of lithium vapor in the range of 500～600nm pumped by XeF （351.1nm）and N₂（337.1nm）UV lasers with He and Ar as buffer gases is reported and analyzed. The upper and lower energy levels to produce the new emission spectra are discussed primarily. The potential kinetic process in the lithium vapor is given. Four superfluorescence lines are reported.更多还原
