摘要：

The laser-induced nonlinear optical response of micellar lyotropic liquid crystals in the nematic and isotropic phases is presented. The Z-scan technique is used to measure the amplitude and the sign of the nonlinear refractive indices of the lyotropic mixture. The amplitude of the nonlinear refractive indices (similar to -10(-6) esu) is two orders of magnitude smaller than the one observed in thermotropic liquid crystals. The effect of the ferrofluid doping is also discussed, [S1063-651X(99)14103-5].
