Abstract

The invention relates to a conductive polymer nonlinear optical material and a method for regulating and controlling the nonlinear absorption performance of a conductive polymer through chemical doping. The conductive polymer nonlinear optical material is composed of a conductive polymer and a strong electron donor chemical dopant, wherein the strong electron donor chemical dopant is used for changing the energy band structure of the conductive polymer through chemical doping so as to realize regulation and control of the nonlinear optical performance of the conductive polymer.
