The transient optical Kerr effect (OKE) and optical induced absorption of emeraldine base (EB) in dimethylformamide solution have been investigated with femtosecond laser pulses.Only a ultrafast component of OKE of EB solution is observed and its dephasing time is given by theoretical fitting.The third-order nonlinear optical susceptibility of EB solution is also determined.Two-photon absorption is proved to be the predominant mechanism causing the observed optical limiting behavior.
