Abstract

We have studied light induced deformations in dye doped liquid crystal elastomers. At high intensities, the incident light causes the elastomer to deform, and the reflected light from the deformed elastomer surface produces an intensity dependent diffraction pattern in the far field. We discuss the experimental observations, and relate these to the processes leading to photoinduced surface relief.
