到目前为止，已观察到许多碱金属卤化物离子准分子（ＡＸ）＋、稀有气体碱金属离子准分子（ＲｇＡ）＋、稀有气体卤化物离子准分子（ＲｇＸ）＋、同核和异核稀有气体离子准分子的荧光谱以及Ｃｓ２＋Ｆ－离子准分子的光学增益现象和Ａｒ的离子准分子激光振荡现象。从光谱学和动力学的角度描述这些离子准分子研究的进展，并指出快速、高强度、大体积和均匀泵浦是实现离子准分子布居反转的关键所在。 To date, many alkali metal halide ion excitons (AX) +, rare gas alkali metal ion excitons (RgA) +, rare gas halide ion excitons (RgX) +, homonuclear and heteronuclear rare Fluorescence spectra of gas ion excimer, optical gain of Cs2 + F- ion excimer and ion excimer laser oscillation of Ar. The progress of these ion excimer studies is described both spectroscopically and kinematically, pointing out that fast, high-intensity, large-volume and uniform pumping are the keys to the inversion of ion quasi-molecular population.
