Abstract

Self-diffraction of light on transient holographic index gratings has been measured in dye-doped twisted nematic liquid-crystal cells. The mechanism of gratings formation is connected with bulk photoconductivity which results in electric field induced torques causing local director axis reorientations. Time evolution of grating recording, voltage and polarization-configuration dependencies were examined. In the self-diffraction experiments the beam coupling effects were observed.
