N2 - The cross section for three-photon ionization of ground-state krypton at λ=193 nm (ArF laser) has been determined. In these experiments, a microwave-absorption technique provided real-time detection of electrons along with measurements of the absolute electron density. Due to a two-photon resonance with the 6p[(3/2)]2 level, the photoelectron number density was observed to vary quadratically with ArF laser intensity for IArF beyond 50-100 MW cm-2 and Kr pressures below 50 Torr.
