摘要

In this study, we performed theoretical analysis and experimental measurement of third harmonic generation (THG) in melanin solution with different concentrations. As predicted by theory, only THG at glass/solution interface was observed due to Guoy phase shift effect. We have shown that this interfacial THG intensity is strongly affected by index matching condition between the two media, leading to minimal THG at a certain melanin concentration. By fitting the dependence of THG intensity versus melanin concentration, linear and nonlinear electric susceptibilities of melanin are obtained, providing a valuable tool to characterize optical properties of biological molecules.
