A chemically modified poly(fluorene-alt-benzothiadiazole) (PFBT) polymer film is reported to exhibit high two-photon absorbing capability and chemical/physical stability upon the action of high-power laser pulses of 780 nm wavelength and 160 fs duration. A nonlinear transmission measurement is conducted by varying the input intensity from 20 to 600 GW / cm 2 , the corresponding nonlinear transmission of a 70 μm thick film is reduced from 0.8 to 0.18, indicating a superior optical limiting behavior. In the meantime, intensity fluctuation of laser pulses can be significantly reduced after passing through the same film sample. Based on the intensity-dependent nonlinear attenuation mechanism, a straightforward optical reshaping effect on spatio-temporal profiles of the laser pulses has also been demonstrated.
