Light-induced anchoring of the molecular director is reported to be an efficient method for writing permanent holographic gratings in dye-doped liquid crystals. We have achieved higher sensitivity and spatial resolution in these materials with other methods. An energy density as low as 10-1 J/cm2 was sufficient to write gratings with a resolution higher than 100 lines/mm.
