Abstract

Poly(indenofluorene) shows a strong degenerate four-wave mixing (DFWM) response when it is excited with 100-fs pulses at 800 nm. The DFWM signal scales with the 1.5 power of the input intensity, which we interpret as being due to absorption saturation phenomena. The saturation was studied by open-aperture Z scan in dilute solutions of poly(indenofluorene) in chloroform. The changes in the absorption coefficient α are described by the formula α = α₀/[1 + (I/I_sat)^1/2], where I_sat is the saturation intensity, which is found to be of the order of 100 MW/cm².
