Paper Abstract

We present the study of optical nonlinearities of nematic liquid crystals under the influence of an external (AC) electrical field. The Z-scan technique is employed as the experimental method to observe and monitor the nonlinear effect. The split-step method is used to model the beam propagation in the liquid crystal sample, and hence derive the far-field intensity distribution, from which the theoretical Z-scan curves are calculated.
