在海军研究实验室的ELECTRA发生器上进行的一系列实验中，我们测量了Ar-Xe激光主跃迁(1.733μm)的激光输出与初始气体温度和Xe浓度的关系。数据表明，当激光气体中Xe含量较高时，激光输出对气体温度的敏感性较低。分子离子ArXe+的破坏速率随气体温度的升高而迅速增加，而Xe2+的破坏速率则不随气体温度的升高而增加。用动力学模型解释，这些数据表明Xe2+和ArXe+对ArXe激光的泵浦都有贡献。
In a series of experiments on the Naval Research Laboratory's Electra generator, we have measured the dependence of the laser output in the principal (1.733μm) transition of the Ar–Xe laser upon both initial gas temperature and Xe concentration. The data show that the laser output is less sensitive to gas temperature when the laser gas contains more Xe. The destruction rate of the molecular ion ArXe+ increases rapidly with gas temperature, but that of Xe2+ does not. Interpreted with a kinetics model, these data indicate that both Xe2+ and ArXe+ contribute to the pumping of the ArXe laser.
