中文摘要：
通过在溶胶-凝胶工艺中引入不同的有机改性硅先驱体，将激光染料PM567掺杂于锆．有机改性硅酸盐凝胶玻璃（Zr-ORMOSIL）中。通过旋涂法，将所得的Zr-ORMOSIL溶胶旋涂在载波片上，并测量了薄膜的折射率和厚度。在紫外连续辐照下，以染料荧光强度下降的幅度来表征染料在介质中的光学稳定性。实验结果表明：有机改性体的适当加入可提高染料的光稳定性，染料在乙烯基三乙氧基硅烷（VTES）、甲基三乙氧基硅烷（MTES）中，光稳定性较好。当Zr的含量为25％或50％时，激光染料PM567具有较好的光稳定性。随着Zr含量的增加，波导薄膜的折射率增加。综合考虑光稳定性和折射率，可对染料掺杂Zr-ORMOSIL波导薄膜的制备工艺进行优化。以Nd：YAG激光器作为光源，实现了激光染料掺杂Zr-ORMOSIL薄膜的动态分布反馈（DFB）的连续可调谐激光输出。
英文摘要：
Pyrromethene and Perylene dyes were doped into zirconia-organically modified silicates （ORMOSILs） by sol-gel process, respectively, with VTES, MTES, ETES, TMSPM and KH560 as organic modifiers. Dye-doped zirconia and zirconia. ORMOSIL films were fabricated by spin-coating on glass substrates with the final solutions. The waveguiding characteristics of the thin films such as refractive index and the film thickness were measured. The effects of zirconia contents and organically modified precursors on the photostability of the laser dyes doped into films were investigated by measuring fluorescence intensity dependence of the films on exposure time under UV irradiation. The most appropriate zirconia content was found to be 50%. KH560 was found to be the worst precursor, whereas VTES was one of the best. DFB （distributed feedback） laser action was induced in the waveguide structure by the crossing beams of a frequency-doubled neodymium：YAG laser. Tunable DFB laser action was also achieved in the asymmetric waveguides.
