Abstract
We show that the theory of the third-order nonlinear susceptibility of semiconductor microcrystallites with a radius much greater than the exciton radius (``weak confinement'') has big intrinsic uncertainties due to the unknown volume dependence of the phenomenological relaxation times. These dependencies are actually sources of another type of optical nonlinearity. The third-order susceptibility increases strongly with the increasing radius of the microcrystallite in the range between 10 and 100 exciton Bohr radii and approaches a well-defined infinite radius limit.
