| Abstract: | In this paper, we study the potassium 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 rate of excitation and ionization and the interaction time respectivily, and obtained the conditions on the photon flux and fluence for saturated excitation and ionization. Last we carry out a series of discussion. |
