Absolute excited state and ion densities from two- and three-photon processes in some 6p levels of atomic krypton

Abstract

Neutral krypton atoms are excited from the ground state to the 4p56p[3/2]2 state by two-photon absorption from an ArF excimer laser operating at 193.41 nm. The third photon ionizes the krypton atoms. Excitation and ionization yields are theoretically computed employing the standard laser rate-equations analysis. Measurements are made on both the excitation and ionization yields. The experimental results are in good agreement with the theoretical predictions of our formulations, as well as with those of other authors.
