摘要

The nonlinear optical properties of P3HT in orthodichlorobenzene were investigated by Z-scan technique using sec-ond harmonic generation(532 nm)of mode-locked Nd:YAG laser in the picosecond domain.The experimental results show the magnitude of their nonlinear refraction indices was up to the order of 10-11 esu.The reverse saturable ab-sorption of P3HT solution was observed and their nonlinear absorption coefficients reach up to 3.4 cm/GW.The strong optical nonlinearity of P3HT may find its new application in the photoclectric field.
