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结晶技术(即,钐原子热处理和过渡金属原子热处理),并开发新的光学功能器件。获得了以下结果。(1)在Sm_2O_3-Bi_2O_3-B_2O_3系玻璃中,我们通过改变激光(波长为1064 nm的连续Nd:YAG激光)的照射方向,成功地写入了具有二阶光学非线性的弯曲晶体线。由于在弯曲点之前和之后,线中晶体的结晶方向保持不变,并且在弯曲点处没有观察到明显的光散射,因此建议在本研究中图案化的晶体线可以用作光波导。此外,澄清了结晶线的表面是光滑的,并且任何可感知的结构 ...更多信息 在弯曲点处不存在紊乱。(2)发展了一种新的激光诱导晶化技术--“过渡金属原子热处理”代替钐原子热处理。在这种新技术中,少量(~ 1mol%)的过渡金属离子在激光辐照部分引起足够的温度升高,并成功<0.5><0.5>地在玻璃表面形成了LiNbO_3,Sr_Ba_Nb_2O_6,Gd_2(MoO_4)_3,Ba_2TiGe_2O_8等多种晶体线。(3)提出了一种新的玻璃表面微加工技术,采用激光辐照和化学刻蚀相结合的方法,在BaO-TiO_2-GeO_2玻璃表面上加工出内径为10μm的微通道。该技术可应用于晶线附近的电极图案化。(4)我们证明了各种具有光学非线性/铁电功能的晶体线图案由我们开发的激光诱导结晶技术。这一研究将对材料和功能器件的科学与技术产生重大影响。少
