Abstract

We report the experimental study of the enhanced backscattering from a random rough surface through dye-doped polymer. The sample is a two-dimensional rough gold surface with a large slope coated with Pyrromethene-doped polymer layer. The sample is illuminated with an s-polarized He-Ne laser, which is pumped by a CW Argon Ion laser. The amplified scattering is measured. It is found that the enhanced backscattering peak is sharply increasing and the width is narrowing for a sample with low dielectric constant (epsilon) ₂ .
