Abstract
We report the observation of a self-switching effect from an opaque to a tr ansparent state occurring at a critical incident intensity in a polymer dis persed liquid crystal. This self-transparency effect is analysed taking int o account the beam profile variations of the light propagating inside such a medium. A clear self-confinement of the laser beam travelling in this com posite material is also presented.
