摘要：

The contribution of one-dimensional exciton states to third-order nonlinear optical (NLO) responses has been investigated on conjugated polymer polydiacetylenes (PDAs). The phase and modulus of complex chi(3)( - 3omega; omega, omega, omega) values have been evaluated for vacuum-deposited blue-form PDA films by means of third-harmonic generation measurements over a wide range of fundamental photon energy. The two-photon resonance effect for the 1A(g) exciton state as well as the three-photon resonance effect for the 1B(u) exciton state have been experimentally probed. The results are discussed in terms of a three-level model deduced from electro-absorption spectra.
