双光子吸收（two-photon absorption）是介质通过中间虚态同时吸收两个光子从基态跃迁至激发态的过程;其跃迁量子特征具有高度空间分辨率和良好介质穿透性,因而在三维微纳加工制作、三维光信息存储和三维荧光显微成像等高科技领域具有应用价值,成为当前有机光电子领域热点课题。该文介绍本课题组十年来在双光子科学领域中开展的工作与相关成果。

Two-photon absorption（TPA） is a nonlinear optical process,which can be described theoretically that a molecule can be excited from the ground state（S0） to the ？rst excited singlet state（S1） by simultaneous absorption of two photons.The research into materials with large TPA cross sections is now attracting increasing attention due to the potential applications of such materials in areas such as optical data storage,optical power limiting,two-photon polymerization microfabriction and two-photon pumped（TPP） up-conversion lasing and so on.In this paper,the progress about two-photon absorbing effect application in our group is reported.
