| Abstract: | In this paper, the laser resonance ionization of atom Al by Nd:YAG and it's pumped dye laser was theoretically investigated. The rate equation for a three level system was solved and the analytical solution was obtained. The absorption cross section of ground and excited electronic state were calculated. The dependence of the ionization efficiency on the rate of excitation and ionization and the interaction time, and the conditions on the photon flux and fluence for saturated excitation and ionization were obtained. Last a series of discussion was followed. |
