Paper Abstract

The film laser concept has attracted much attention from both fundamental and practical points of view. However, to obtain a very thin film encounters the difficulty in realizing ultrahigh doping level of rare earth ions in a very thin film. In this work, a series of transparent Er3+/Yb3+ co-doped Al2O3-SiO2 / P2O5-SiO2 glass thin films with rare earth ions doping level up to 20 mol% were fabricated by sol-gel spin-coating method. The roughness value of film surface was characterized with AFM technique. The luminescent spectra and the corresponding FWHM of Er3+/Yb3+ co-doped films are compared and some other spectroscopic properties are discussed.
