    • The integral of eq 1 really describes the number of photon interactions with the electromagnetic field, rather than the number of absorbed photons. However, discrepancies between the number of photon interactions (absorption or emission) and the number of absorbed photons are negligible, except for the highest fiuences in Figure 3.

    • aff. This procedure is justified since (i) the reflection of the pump beam off the exit interface is negligible, as is (ii) the pump-induced reflection of the probe beam off the entrance interface.

    • The inflection at high pump fluence for the 0.65 eV data is not an artifact and is commented on in the context of eq 5. The dependence of exciton multiplicity on fluence is an interesting subject by itself and will be dealt with in a forthcoming paper. The crossing of the two curves in Figure 3 is due to multiplicity-dependent spectral shifts of the first exciton level, as explained in detail in the section on spectral integration.
