The purpose of this study is to pattern functional single crystal lines such as LiNbO_3 on the glass surface using a laser-induced atom heat method and to clarify their morphology, orientation, and optical functions, giving a breakthrough in the fabrication of functional materials. The studies on the mechanism in the crystallization of glasses in the laser-induced atom heat processing, periodic refractive index changes in ferroelastic β'-Sm_xGd_<2-x>(MoO_4)_3 lines, light confinement in LiNbO_3 crystal lines, the proposal of new micro-fabrication method by a combination of laser irradiation and simple chemical etching, and highly oriented two-dimensional planar crystal patterning were carried out, and consequently, a laser-induced atom heat method was demonstrated to be a general and conventional technique for function single crystal pattering.
