Abstract
The yield of singly- and multiply- charged ions of krypton and xenon is presented as a function of laser intensity and frequency. The measurements were performed using the second harmonic output of a well-characterized, tunable picosecond dye laser in the range 285 to 310 nm at laser intensities from lx1012 to 1014 W/cm2. Enhancement of the Kr+ yield by two orders of magnitude by three-photon resonant, four-photon ionization is observed in the vicinity of the 4d'[5/2]3 and the 4d[3/2)1 intermediate states. A model incorporating line shifts and widths scaling linearly with intensity is in good agreement with the experimental results.
