Abstract

It has been tried to solidify dye laser, but the attempt was not succeeded, yet, for highly fading speed of the laser dyes. We investigated the photofading rate of Rhodamine 6G, the dye for dye laser, in vinyl polymer matrices, and it was found that the fading rate was proportional to e value of the monomer which composes of the polymer.It was also found that the formation of inclusion complex by cyclodextrin was not effective in such polymer matrix containing poly (methyl methacrylate).It was already reported that the photofading of Rho damine 6G in poly (methyl methacrylate) was reduction reaction. This phenomena were due to the fact that the hydrogenated position of Rhodamine 6G was not included in cyclodextrin. On the other hand, the photofading rate of Rhodamine 6G in poly(vinyl alcohol) matrix was very slow and was further decreased by cyclodextrin.
