Light penetration depth is a fundamental property that has been researched extensively with a large amount of materials. Among those studies, different planetary atmospheres and material phases, like plasmas, had been previously addressed, both theoretically and experimentally. However, no experimental data are available for platinum and iron gases due to the difficulties for the creation of gas state from a solid metal material. This work present experimental penetration depths at 532 nm laser light for iron and platinum gases produced by a carefully tuned exploding wire system in atmospheric air. Iron presents a larger dispersion on the data than platinum, which is explained because of its large magnetic permeability value, that generates a less homogeneous gas than in the platinum case.

铂和铁气体在532 nm处的光穿透深度的第一个实验值

光穿透深度是已对大量材料进行了广泛研究的基本属性。在这些研究中，先前曾在理论和实验上讨论过不同的行星大气和物质相（如等离子体）。然而，由于难以从固态金属材料产生气态，因此没有用于铂和铁气体的实验数据。这项工作提出了在532 nm激光下对大气中精心调整的爆炸金属丝系统产生的铁和铂金气体的实验穿透深度。铁在数据上的分散度比铂大，这可以解释，因为铁的磁导率值大，与铂相比，生成的气体更少。
