The dependence of ionization signals of Xe and Kr atoms on the laser intensity has been studied using an ArF excimer laser. For both atoms, we observe a slope of 2 in the log-log plot of the ionization signal versus laser intensity, and saturation of ionization at laser pulse energies higher than about 100 mJ (1.7×1010W/cm2). The ionization of Kr can be interpreted as a 2-photon-resonant, 3-photon (2+1) ionization.
