Abstract

The aim of the present work is to study the spatial coherence of a laser beam travelling through a nematic liquid crystal cell under the application of an electric field. Depending on a) the applied d.c. electric field, b) the orientation of the liquid crystal, and c) the polarization of the incident light beam, the peculiar optical properties of the liquid crystal (induced via the interaction of the electric field with the dielectric anisotropy) allow one to modify almost at will the coherence of the light beam used.
