Summary: | 碩士 === 國立中山大學 === 物理學系研究所 === 91 === Push-pull charge-transfer organic molecules exhibit large second-order nonlinear optical nonlinearity , and have been used to manufacture efficient photonic devices .We study a series of CT molecules by using the two-photon scattering method with a tunable femto-second pulsed-laser to obtain the value of the molecular first hyperpolarizability (β) .We discuss the relationship between theβvalue and chemical structure , and compare theβvalues with the two-level model prediction for several incident laser excitation wavelength.
