Abstract

In top-hat _Z scans that employ tunable sources such as optical parametric generators without line-narrowing gratings, the size of the aperture used to clip the beam may exceed the coherence length, and the variation with z of the transverse profile of the resulting partially coherent beam may differ significantly from that of a perfect top-hat beam. After a careful validation of our experimental set-up, we perform picosecond open-aperture Z scans with a top-hat beam at selected wavelengths in the visible and nanosecond open-aperture Z scans with a spatially Gaussian beam at 532-nm wavelength on a toluene solution of a particular platinum(II) 2,2′-bipyridyl complex bearing naphthalimidylethynyl-substituted fluorenylacetylide ligands. We report values of the singlet and triplet excited-state absorption cross sections of the complex.
