e substantial-good electron π-conjugation observed in all-metallo-organic complexes and porphyrin derivatives are suitable as potential third-order nonlinear optical (NLO) materials application. e central metal ion configuration renders these complexes more advantageous in the nonlinear optical response induced by charge displacement and the effect of the external eld compared to many other organic and inorganic materials. is paper, we assess the linear optical and nonlinear optical properties of tetra-porphine magnesium (MnTPyP)-polymethyl methacrylate (PMMA) composite thin films prepared by a simple coating technique. Based on the Drude model single oscillator calculations, other optical parameters such as dispersion energy, dielectric constant nonlinear refractive index and the third nonlinear susceptibility were evaluated and addressed in detail.
