| Abstract: | Optical storage properties of the azo dye polymer film were studied by degenerating four-wave mixing and holographic optical storage methods. The optical storage mechanism of material mainly results from the trans-to-cis isomerization of azo molecules by illuminating with a resonant light. The real-time and permanent optical storage time constants and the optimal writing beam intensity were obtained by experiments. |
