| Abstract: | The photo bleaching processes in a nonlinear optical polymer film used poly (methyl methacrylate) based dispersive red one (DR1/PMMA) side chain at 488 nm argon ion laser radiation was investigated. The index change of DR1/PMMA film was measured by two beam scan technique. It provides a simple method to determinate the parameters in bleaching model describing the photo bleaching processes of polymer. |
