摘　　要：用Ｎｄ：ＹＡＧ及其泵浦的染料激光进行银原子三步共振电离，求解了非饱和共振过程速率方程，计算出基态和激发态共振吸收截面，给出电离效率分别与激光电离速率以及作用时间的变化关系，得到饱和激发电离的流量条件和通量条件，并进行了分析讨论。In this paper, we study the silver atoms resonance ionization with Nd:YAG and it's pumped dye laser. The rate equations for a three level system are soled in cases of unsaturation resonance process. We calculate the absorption cross section for initial state and excitant state, gained that the ionization efficiency relating to the rate of excitation and ionization and the interaction time respectiveily, and obtained the conditions on the photon flux and fluence for saturated excitation and ionization. Last we carry out a series of discussion.
