Studies on Optical Properties of Polymer as Solid Matrix for Laser Dye

引入极性交联剂(Ⅰ)改性的MMA-MA共聚物作基质,通过研究激光染料Rh6G在不同组成的基质中的吸收光谱、荧光特性和激光能量转换效率的关系,获得含Rh6G的固溶态材料。对材料的光学均匀性作了探讨,材料的激光输出特性达到同条件下的Rh6G乙醇溶液水平,显示了染料在固溶态中激光运转的可能性。

One noteworthy attraction of the use of a solid matrix such as a polymer for dye laser is that it obviates many of the common problems associated with flowing dye systems. In this paper, the optical properties of a modified copolymer of MMA-MA as the main matrix doped with dye Rh6G has been studied, e. g. the absorption spectrum of Rh6G in the materials, fluorescence properties of Rh6G in the materials, and laser conversion efficiency of Rh6G in the material . It has found the maximal laser conversoin of Rh6G in the material is 20%, as high as the level which Rh6G can attain when it is dissolved in ethyl alcohol. The optical homogeneity of the material also has been studied.
