将Nd：YAG激光辐照玻璃写入晶线技术--选择性原子热处理技术应用于稀土（Sm 3+，Dy 3+）钡硼酸盐玻璃，制备出宽度约为5 μ m的非线性光学β-BaB 2 O 4（β-BBO）晶线。在偏光显微镜和二次谐波发生（SHG）测量中，晶体线显示出均匀的颜色。晶体线中的SHG信号的方位角依赖性与市售β-BBO块体单晶中的相同。结果表明，YAG激光写入的晶体线为β-BBO单晶，c轴取向沿着激光扫描方向。(C)2003年，美国物理学会。
The technique for the writing of crystal lines in glass by Nd:YAG laser irradiation, selective atom heat processing, is applied to rare-earth (Sm3+, Dy3+) barium borate glasses, and nonlinear optical beta-BaB2O4 (beta-BBO) crystal lines with a width of similar to5 mum are fabricated. The crystal lines show uniform colors in polarized optical microscope and second-harmonic generation (SHG) measurements. The azimuthal dependence of SHG signals in the crystal lines is the same as that in commercially available beta-BBO bulk single crystals. It is demonstrated that the crystal lines written by YAG laser irradiations are beta-BBO single crystals with the c-axis orientation along the laser scanning direction.
