9. One disadvantage of the self-diffracted DFMW experiment described here is that homogeneous and inhomogeneous transitions cannot be discriminated. Weiner et al. [A.M. Weiner, S. De Silvestri, E.P. Ippen: J. Opt. Soc. Am. B 2, 654 (1985)] have shown that a threepulse experiment is capable of distinguishing between these cases10.1364/JOSAB.2.000654 ↗

14. Recent observations of FWM-signal for T<0 were explained [B.F. Feuerbacher, J. Kuhl, R. Eccleston, K. Ploog: Phys. Rev. B 43, 2439 (1991)] by the contribution of biexciton transitions. We can rule out this effect for our observations noting that the rise has half the time constant of the decay, that the signal disappears for inhomogeneously broadened samples, and that it is independent of the excitation energy10.1103/PhysRevB.43.2439 ↗

34. The only observation of QB in semiconductors, where the optical transitions could not be resolved spectroscopically, was reported in [21]. However, the mechanism of the surprisingly small splitting (a few ?eV) was not clear
35. The theory does not take the polarization interaction into account and is therefore not applicable for T<0. Furthermore, it does not account for finite laser pulses. However, our pulses are considerably shorter than the modulation period, which will prevent a large influence of the pulse shape on the modulation of the QB
