铯原子激光共振电离

Laser Resonance Ionization for Cesium Atoms

用Ｎｄ：ＹＡＧ及其泵浦的染料激光进行铯原子三步共振电离。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。

In this paper,we study the cesium atoms resonance ionization with Nd: YAG andit's pumped dye laser. The rate eqrations for a three level system are soled in cases of unsaturation resonance process We calculate the absorption cross section for initial state and excitantstate,gained that the ionization efficiency relating to the rate of excitation and ionization arid theinteraction time respectivily, and obtained the conditions on the photoll flux and fluence for saturated excitation and ionization. Last we carry out a series of discussion.
