A.C. STARK SHIFT AS A PROBE TO MEASURE A LASER POWER DENSITY DISTRIBUTION AND ITS APPLICATION TO MULTI-PHOTON IONIZATION

In order to perform multi-photon ionization experiments at a particular light intensity, the AC Stark-shift of the xenon 6s level is used as a probe to select that intensity from the range of intensities present in the laser focus. Our analysis provides an accurate, wide-range distribution function of the intensities in our multi-mode laser pulses. Using this method we determined there al order of non-linearity of the resonant ionization process and the probability for additional photon absorption.
