摘要：
The theoretical study of two-photon absorption (TPA) properties of a non-conjugated dimer is related to cooperative effects between monomers. This effect leads to a strong increase of the TPA cross-section. This phenomenon is studied in the case of the three-level model. (C) 2002 Elsevier Science B.V. All rights reserved.
