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.
