Abstract
We provide the first experimental determination of three-photon absorp tion (ThPA) coefficients alpha((3)) in a quasi-bidimensional structure . The measurements of alpha((3)) have been performed on a sample of a ZnSe/ZnS0.18Se0.82 strained-layer superlattice at fixed excitation ene rgies corresponding to the exciton resonances near the direct band gap . The evidence of the ThPA process in such energy range points out the huge enhancement of exciton non-linearities in quantum-confined syste ms.
