Description

Low-pressure Kr and Xe gas has been irradiated by a high-intensity (3 x 10/sup 12/--10/sup 14/ W cm-2), short-pulse (1.3 ps), tunable laser beam. Enhancement of the Kr+ yield by 2 orders of magnitude by three-photon--resonant four-photon ionization is observed at intensities 1 to 2 orders of magnitude above previous results. The 4p→5d [(1/2]1 and 4p→4d [(3/2]1 three-photon Kr resonance profiles are measured as a function of peak laser intensity and are well fitted by a simple model incorporating line shifts and widths scaling linearly with laser intensity
