Laser Induced Crystallization of LAS Glass System Doped with Samarium Ion
Laser induced Crystallized glasses including nonlinear optical crystals have been taken attention, because of a high potential for laser host, tunable waveguide, tunable fiber grating, etc.. Laser irradiation of glass has been regarded as a process for selective structure modification and crystallization in glass, various researches of laser-induced structural changes have been progressed so far. In this work, Li2O–Al2O3–SiO2 (LAS) glass was irradiated by Nd: YAG laser with a wavelength of 1064nm by increasing Sm2O3 contents as a dopant which induces heat processing in a glass. Crystallized glasses by irradiation of Nd: YAG laser has been compared with conventional crystallization heat-treated in an electric furnace from x-ray diffraction analyses. Finally, we could achieve results which laser irradiation affect crystallization of glass by changing crystallinity between Tx and Tp.
