摘要：
We report the observation of a self-switching effect from an opaque to a transparent state occurring at a critical incident intensity in a polymer dispersed liquid crystal. This self-transparency effect is analysed taking into account the beam profile variations of the light propagating inside such a medium. A clear self-confinement of the laser beam travelling in this composite material is also presented.
