Abstract

In this study, the Stark broadening of the visible triplet of neutral oxygen was caracterised. To cover a wide range of electron densities, the study relies on two joint experimental campaigns: one on laser-induced plasma and the other on wall-stabilized arc. Measuring the Stark impact factor associated with the triplet requires, in addition to an accurate measurement of electron density and temperature, isolating the Lorentzian Stark contribution by deconvoluting the experimental spectral profile. This measurement will allow, for any observation where the triplet is unresolved and/or suffers from line overlapping, to estimate the electron density or perform elemental quantification from the total broadening of the O

777

nm triplet.

中性氧777纳米三重态Stark展宽的深入研究

在这项研究中，中性氧的可见三重态的斯塔克拓宽的特点。为了覆盖更大范围的电子密度，这项研究依赖于两个联合实验：一个是激光诱导等离子体，另一个是壁面稳定电弧。测量与三重态相关的斯塔克影响因子，除了需要精确测量电子密度和温度外，还需要通过反卷积实验光谱剖面来分离洛伦兹斯塔克贡献。这种测量将允许，对于任何观测，在三重态未解析和/或遭受线重叠，估计电子密度或执行元素量化从总拓宽的o777nm三重态。
