Abstract
We study the chaotic dynamics which occurs in a nematic liquid crystal film during the director reorientation induced by an intense optical field. We show the presence of intermittency in the fluctuations of th e transmitted Light intensity polarized perpendicularly to the inciden t beam. The intermittency can safely be described by the multifractal geometry, and, in this framework, we present a simple heuristic model for the phenomenon.
