Abstract
The intensity distribution in the focal region of a laser bearn is cal culated for a Gaussian profile truncated by a circular aperture. The r esults give the theoretical ionization volume as a function of the las er intensity and this allows calculation of the multiple ionization of atoms by an intense laser. As an example, the yields of multiply char ged ions of xenon are calculated for focused intensities in the range 10(13) to 10(16) W cm-2. Oscillations in the yield curves are produced , with an implication that this behaviour may explain some experimenta l observations.
