摘要
以准静态隧道电离理论为基础, 建立了描述圆偏振光场电离电子能量分布的简单模型。 与现有的理论计算及实验结果的比较表明, 该模型数学推导简单、 物理意义明显, 可用于研究较高电子温度和(或)较低电子密度的光场电离等离子体参数。
Abstract
A simplified model is established to describe the electron energy distribution in circularly polarized optical-field ionized plasmas, based on quasi-static tunneling ionization theory. Comparisions with existing calculations and experimental result show that it can be used to study OFI plasmas with higher electron temperature and/or lower electron density.
