Abstract

Diffractive properties of temporary holographic gratings were studied in cells of the homogeneously aligned nematic E7 doped with a trace of carbon nanotubes. These phase gratings were induced by interference modulation of the pulsed wave-train excitation of two coherent writing beams, in conjunction with an externally applied dc voltage. The effects of the optical excitation on the diffraction efficiencies and the decay time constants were observed to be strongly dependent on the pulse width of the writing beams.
