在Sm_2O_3-SrO-BaO-Nb_2O_5-B_2O_3系统中，研制了一种新型玻璃，该玻璃具有Sm_3+掺杂的Sr_xBa_（1-x）Nb_2O_6（SBN）铁电体的晶化特性，并在连续Nd：YAG激光（波长：1064 nm，功率：1 W）辐照下，钐原子热处理，已被审查。通过X射线衍射分析、显微拉曼散射光谱、二次谐波产生光谱和光致发光光谱证实了Sm ~（3+）掺杂SBN非线性光学晶体的形成。用Nd：YAG激光在10 Sm_2 O_3·10 SrO·10 BaO·20 Nb_2 O_5·50 B_2 O_3（mol%）等玻璃表面写入了直径为20-70μm的Sm ~（3+）掺杂SBN晶体点和宽度为20-40μm的线，点的照射时间为20- 70 s，线的扫描速度为1-5μm/s。本研究表明，钐原子热处理具有潜在的图案化的光波导组成的铁电SBN晶体在玻璃基板。
New glasses giving the crystallization of Sm3+-doped SrxBa1−xNb2O6(SBN) ferroelectrics have been developed in the Sm2O3−SrO−BaO−Nb2O5−B2O3system, and the formation of SBN crystal dots and lines by continuous wave Nd:YAG laser (wavelength:1064nm, power: 1W) irradiations, i.e., samarium atom heat processing, has been examined. The formation of Sm3+-doped SBN non-linear optical crystals is confirmed from X-ray diffraction analyses, micro-Raman scattering spectra, second harmonic generations, and photoluminescence spectra. Sm3+-doped SBN crystal dots with the diameters of 20–70μm and lines with the widths of 20–40μm are written at the surface of some glasses such as 10Sm2O3·10SrO·10BaO·20Nb2O5·50B2O3(mol%) by Nd:YAG laser irradiations with the irradiation times of 20–70s for the dots and with the scanning speeds of 1–5μm/s for the lines. The present study suggests that the samarium atom heat processing has a potential for the patterning of optical waveguides consisting of ferroelectric SBN crystals in glass substrates.
