锰原子激光共振电离

Laser Resonance Ionizaion for Manganese Atoms

用Ｎｄ：ＹＡＧ泵浦的染料激光进行锰原子三步共振电离。求解了非饱和共振过程速率方程，计算出基态和激发态吸收截面，给出电离效率分别与激发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，并进行分析讨论。

in this paper, We study the manganese atoms resonance ionization with Nd: YAGpumped dye laser. The rate eqrations for a three level system are soled in cases of unsaturationresonance 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 respectivily, and obtained the conditions on the photon flux and fluence for saturatedexcitation and ionization.
