  1. Khoo, IC; Guenther, BD; Wood, MV; Chen, P; Shih, M-Y, Coherent beam amplification with a photorefractive liquid crystal, Optics Letters, vol. 22 no. 16 (1997), pp. 1229-1231 .

    This report discusses the enhancement of the beam-coupling effect with the use of a more efficient photocharge-producing dopant such as fullerene C60 and a much larger effective applied dc field in thinner liquid-crystal films. More importantly, it is shown that the beam-amplification process is accompanied by negligible phase cross talk between pump and the signal beams similar to those observed in photorefractive crystals.
