论文摘要
我们提出了由激光脉冲对气体或固体的影响形成的等离子体云中电场概率分布函数的一般表达。我们还介绍了该函数的数值计算结果，该函数根据等离子云的大小而在非相互作用粒子的情况下。它考虑了电荷不平衡引起的离子微菲尔德和大型菲尔德。随着电荷不平衡的增加，观察到大型场值的分布函数急剧增加的影响。获得了光谱线移动的计算与实验之间的良好一致性。获得的结果对于在各种应用中诊断血浆至关重要。
We present a general expression for the probability distribution function of electric field in a plasma cloud formed by the impact of a laser pulse on a gas or a solid body. We also present the results of numerical calculation of this function for the case of non-interacting particles depending on the plasma cloud size. It takes into account the ionic microfield and the macrofield arising from the charge imbalance. As the charge imbalance increases, the effect of a sharp increase in the distribution function for large field values is observed. Good agreement between the calculation of the shift of the spectral line and the experiment is obtained. The results obtained are of crucial importance for diagnosing plasma in various applications.
