| 摘 要： | 本文就Ｎｄ：ＹＡＧ及其泵浦的染料激光进行钠原子三步共振激光发电离，求解了非饱和共振过程的速率方程。在一些典型实验条件下，计算出基态和激发态的共振吸收截面，给出电离效率分别与二步激发速率，电离率速率以及作用时间的变化关系，得出饱和激发电离的流量条件和通量条件等，并进行了一系列讨论。

| Abstract: | In this paper, we use Nd: YAG and its pumped dye laser for sodium'S laser resonance ionization in which three energy levels are adopted. Under some typical conditions, we calculate the absorption cross sections for the ground state and the resonant state. By solving the rate equation of laser resonance ionization, we calculate and discuss the laser resonance ionization efficiency, and obtain a flux condition and a fluent condition for resonance ionization saturation. |
