It should be pointed out that inherent in the nonlinear absorption (transmission) measurement using either nanosecond or picosecond laser pulses is the assumption that the two-photon process is the predominant mechanism responsible for the observed intensity-dependent nonlinear absorption. However, it is now well recognized that the strong TPA process increases molecular populations considerably in excited states, and thus a secondary process, i.e, the cascaded one-photon absorption from the excited states, may greatly enhance the observed nonlinear absorption of the input laser beam. Since it is difficult to separate these two contributions through the nonlinear absorption measurement in these time regimes, the term effective TPA cross section is used to describe the apparent δ values under these excitation c

Since it is difficult to separate these two contributions through the nonlinear absorption measurement in these time regimes, the term "effective TPA cross section" is used to describe the apparent δ values under these excitation conditions for the two-photon chromophore. The effective cross section of a TPA chromophore can be more than 2 orders of magnitude larger than the intrinsic cross section obtained via a femtosecond masurement, depending on the type of technique (transmission or fluorescence method) used.
