摘要：
A time-resolved z-scan technique using 100 fs laser pulses for measurement of nonlinear refractive indexes is reported. This technique allows us to measure the relaxation times of the nonlinear refractive indexes. Both the magnitude and the relaxation of nonlinear refractive indexes in CS, and head-to-tail poly(3-alkylthiophene) were measured. We found that there are two decay components. The slow and the fast components come from thermal effects and dielectric effects, respectively. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
