项目摘要

The purpose of the present study is to fabricate the patterning of crystal lines on the surface of glasses through the application of laser-induced crystallization techniques (i.e., samarium atom heat processing and transition metal atom heat processing) developed by our research group and to develop new optical functional devices. The following results were obtained.(1) In Sm_2O_3-Bi_2O_3-B_2O_3 based glasses, we succeeded in writing of curved and bending crystal lines showing second order optical nonlinearities by just changing the laser irradiation (continuous wave Nd:YAG laser with a wavelength of 1064 nm) direction. As the crystallographic direction of crystals in the lines was hold before and after the bending point and apparent light scattering was not observed at the bending point, it is proposed that the crystal lines patterned in this study can work as optical waveguides. Furthermore, it was clarified that the surface of crystal lines is smooth and any appreciable structural … More disorders are not present at the bending point.(2) A new laser-induced crystallization technique called "transition metal atom heat processing" instead of samarium atom heat processing was developed. In this new technique, a small amount (-1 mol%) of transition metal ions induces sufficient temperature increases in the laser-irradiated part, and various crystal lines such as LiNbO_3, Sr_<0.5>Ba_<0.5>Nb_2O_6,β'-Gd_2(MoO_4)_3, Ba_2TiGe_2O_8 were patterned successfully on the glass surfaces.(3) A new micro-fabrication technique on the glass surface using a combination of laser irradiation and chemical etching was proposed, and micro-channels with an inner diameter of 〜10μm were patterned on the surface of BaO-TiO_2-GeO_2 glasses. This technique would be applied for the patterning of electrodes at the vicinity of crystal lines.(4) We demonstrated that various crystal lines with optical nonlinear/ferroelectric functions are patterned by laser-induced crystallization techniques developed by us. This research would give a great impact in the science and technology of materials and functional devices. Less

本研究的目的是通过应用激光诱导的结晶技术（即，由我们的研究组开发的samarium Atom热处理和过渡金属加热处理）和开发新的光学功能设备，通过激光诱导的结晶技术（即samarium Atom热处理和过渡金属热处理）来制造晶体线的图案。（1）在SM_2O_3-BI_2O_2O_3-B_2O_3基于玻璃杯中，我们成功地撰写了弯曲和弯曲的晶体线，显示了二阶光学非线性，仅通过更改激光辐照（连续波ND：YAG LASER：YAG LASER，其波长为1064 nm nm）。由于在弯曲点之前和之后保持了线中晶体的晶体学方向，并在弯曲点未观察到明显的光散射，因此提出在这项研究中模仿的晶体可以作为光学波导起作用。此外，可以澄清的是，晶体线的表面是光滑的，任何令人欣喜的结构……在弯曲点不存在更多的疾病。（2）一种新的激光诱导的结晶技术，称为“过渡金属原子热处理”，而不是SAAMARIUM ATOM ATOM HEAM PROCESTIC。在这项新技术中，过渡金属离子的少量（-1摩尔％）诱导激光辐照部分的足够温度升高，以及各种晶体线，例如linbo_3，sr_ <0.5> ba_ <0.5> ba_ <0.5> nb_2o_6，β'-gd_2（moo_4），em_3，ba_3，ba_3，ba_2 taptaptaptaptaptaptial of pataptile ot and papter。提出了一种在玻璃表面上使用激光照射和化学蚀刻的组合在玻璃表面上的新微型制作技术，并在BAO-TIO_2-GEO_2玻璃杯的表面上对内径约为10μM的微通道进行了图案。（4）我们证明了具有光学非线性/铁电函数的各种晶体线是由我们开发的激光诱导的结晶技术图案化的各种晶体线。这项研究将对材料和功能设备的科学和技术产生重大影响。较少的
