A previous approximation scheme [6] which allowed to calculate, in a simple manner, the quantity An2/% (n mea.n value and An2 variance of the photon number) in the course of a multi-photon absorption process, is extended to study the change of the shape of the photon distribution, too. It turns out
The fluorescence spectrum of 7-hydroxycoumarme m ethanol excited by a pulsed tunable dye laser reveals different features when excitation proceeds via one-photon and two-photon absorption. In the former case the spectrum shows two peaks delayed in time by approximately 2 ns and characterized by diff
