Abstract:
I will describe a new robust method for
determining saturation peak intensities of
multiple non-linear intense field processes
simultaneously. The Z-scan method takes
advantage of the balance between the non-
linear response and interaction volume change
as an intense laser pulse is focused onto a
sample. A geometric factor is derived, directly
relating peak intensity at optimal target
displacement from focal plane and the
corresponding saturation intensity with no need
of a-priori assumptions about the non-linear
process. The method is demonstrated
experimentally for intense laser pulse
interaction with molecular anions.
