报道了掺氦激光晶体中氦注入光波导的光学和结构特性。用棱镜耦合方法研究了632.8 nm波长下的暗模特性。在808 nm激光二极管的激发下，实现了紫外光、蓝光、红光和近红外荧光的自发发射。用高分辨X射线衍射仪表征了离子辐照对薄膜结构性质的影响。结果表明，在室温下，当He离子注量为1.5×1016ion/cm2时，经2.8 MeV He离子辐照后，晶体的初始发光性能略有改变。
We report the optical and structural properties of helium-implanted optical waveguides in Nd:MgO:LiNbO3laser crystals. The prism-coupling method is used to investigate the dark-mode properties at the wavelength of 632.8 nm. The spontaneous generation of ultraviolet, blue, red, and near-infrared fluorescence emissions is demonstrated under excitation with an 808-nm laser diode. The effects of ion irradiation on the structural properties are characterized using the high-resolution X-ray diffraction technique. The results show that the initial luminescence properties of Nd:MgO:LiNbO3crystals are slightly modified by irradiation with 2.8 MeV He ions at fluences of 1.5 × 1016ions/cm2at room temperature.
