How to Model Two-Photon Absorption

Hi, I am trying to model the two-photon absorption (TPA) process in a nanostructure using COMSOL Multiphysics. For describing light propagation, I am using the Wave Optics Module.
My main question is how many physics interfaces are required to properly model this process .
I would greatly appreciate any guidance on the choice of appropriate physics interfaces and the practical steps needed to implement two-photon absorption in COMSOL.
In addition, if anyone could point me to an example model or a COMSOL application that demonstrates two-photon absorption, or more generally multiphoton absorption, I would be very grateful.
