Cascading is the process by which second order nonlinearities, when used near phasematching for parametric mixing processes such as second harmonic generation (SHG), can be used to mimic some effects normally associated with third order nonlinearities, more specifically with an intensity-dependent refractive index. The findmental beam on transmission through a x(2)-active medium has the form:
