| Abstract: | This paper discusses the process of resonant laser ablation(RLA),where the two step three photon resonant ionization of copper is considered as the best scheme.The rate equations of resonant ionization of copper are calculated and the factors that affect the ionization efficiency are discussed.The results prove the potential advantages of RLA especially the low energy threshold. |
