Perturbative nonlinear optics consists of many powerful predictive theoretical methods, including\ the perturbative series of observables related to the interaction of light with matter. The\ light intensity limits of such series have been studied in the past for highly nonlinear processes\ such as above threshold ionization and high harmonic generation. A more recent debate focuses on\ the limits of applicability of perturbation theory for the nonlinear electrical susceptibility and the\ nonlinear index of refraction of atoms, which are important parameters to study, for example, for filamentation of laser pulses in nonlinear media.
