Nonlinear optical properties and holographic recording performance of methyl orange doped polymer films

In conclusion, solid and liquid matrices and changing pH of methyl orange showed no significant difference in the degenerate four wave mixing (DFWM) results. Holographic recording in methyl orange doped films was observed only in the basic form of the azo dye. The increased damage threshold and decreased humidity sensitivity however, make the epoxy films much more attractive for practical applications even with the increased write/erase cycle time over the PVA films.<
