Abstract

The performance of a recently developed nonlinear optics epoxy-based polymer with covalently attached dye molecules is investigated. Large refractive nonlinearity is observed. The refractive index nonlinear coefficient and relaxation time were measured using a degenerate two beam coupling scheme with a frequency doubled Nd³⁺:YAG laser. We have used a thin polymer film for dynamic holography recording. Peculiarities of self diffraction at the holograms are discussed for both dynamic and stationary hologram recording. The possibility to write and erase phase gratings reversibly by ns-pulses and store information for hours are demonstrated. An analysis of possible mechanisms for the refractive index nonlinear behavior is presented. The results vividly manifest the possibility of the polymer to be used as reversible medium for information storage. Besides, the polymer structure in question exhibits both ns and quasi-stationary response together with simplicity of fabrication and low prices which have wide prospects for different applications in the field of optical data processing.
