Abstract

We demonstrate, for the first time to our knowledge, the use of a photorefractive polymeric composite to clean a phase-distorted laser beam and reconstruct a badly distorted image. Advantageous qualities including relatively high figures of merit, ease of processability, and low cost make this class of materials attractive when compared with their inorganic crystalline counterparts. In addition, we used four-wave-mixing and holographic techniques to obtain an internal diffraction efficiency of ∼31% at 54.5 V/μm and a two-beam-coupling gain coefficient of Γ = 17 cm-1 at 54.5 V/μm under our experimental conditions.
