Abstract
Linear and nonlinear optical properties of a ladder polymer based on t he poly(p-phenylene) backbone (LPPP) have been investigated. Femtoseco nd degenerate four-wave mixing (DFWM) was used for the determination o f the nonlinear refractive index n(2) at 800 nm, Values of \n(2)\=(3-7 )x10(-13) cm(2)/W were obtained from DFWM measurements on thin films a nd solutions of the polymer, The two-photon absorption coefficient of LPPP is estimated to be beta=5x10(-9) cm/W at 800 nm.
