采用连续波Nd:YAG激光（波长λ = 1064 nm）照射含过渡金属（TM）离子（Fe2+、Ni2+和V4+）的玻璃，研究了在玻璃中书写晶线的技术。激光能量通过TM离子的d-d跃迁被吸收，并通过非辐射弛豫过程耗散到TM离子周围的晶格中，使激光照射区域温度升高并诱导结晶。在NiO Fe2O3-和v2o5掺杂（0.3-1 mol %）的BaO-TiO2-GcO(2)和BaO-TiO2-SiO2玻璃中，该技术已被证明可以写出由非线性光学fresnoite型Ba2TiGe2O8和Ba2TiSi2O8晶体组成的晶线。证实了晶体线中的晶体沿激光扫描方向具有高度定向。在这项研究中开发的技术被提议称为“过渡金属原子热处理”。(c) 2006年美国物理研究所。
A technique for the writing of crystal line in glass has been developed, in which a continuous-wave Nd:YAG laser (wavelength: lambda = 1064 nm) is irradiated to the glasses containing transition metal (TM) ions such as Fe2+, Ni2+, and V4+. Laser energies are absorbed through d-d transitions of TM ions and dissipated to the lattice surrounding TM ions by nonradiative relaxation process, giving the increase in temperature in the laser irradiated region and inducing crystallization. This technique has been demonstrated for the writing of crystal lines consisting of nonlinear optical fresnoite-type Ba2TiGe2O8 and Ba2TiSi2O8 crystals in NiO Fe2O3-, and V2O5-doped (0.3-1 mol %) BaO-TiO2-GcO(2) and BaO-TiO2-SiO2 glasses. It is confirmed that crystals in the crystal lines are highly oriented-along the laser scanning direction. The technique developed in this study is proposed to be called "transition metal atom heat processing." (c) 2006 American Institute of Physics.
