摘　　要：α轴向Ｎｄ：ＭｇＯ：ＬｉＮｂＯ_３单晶光纤的镁离子内扩散显微特性研究阙文修，姚熹（西安交通大学电子材料研究室，西安７１００４９）霍玉晶（清华大学电子工程系，北京１０００８４）提要：α轴向生长的Ｎｄ：ＭｇＯ：ＬｉＮｂＯ_３单晶光纤经镁离子内扩散以改变其表...A magnesium-ion indiffusion process is employed to change the surface layer component of theα- axis Nd:MgO:LiNbO3single crystal fiber.It is shown by electron probe microanalysis that magnesium-ions have completely diffused intothe bulk of crystal fiber and magnesium-ions concentration distribution along crystal fiber axial have a parabolic profiles. It is proved by Lane X- ray diffraction and scanning electron microscopy that magnesium-ion indiffusion does not affect the crystalline property of crystal fiber and crystal fiber preserves goodsing le-crystal structure.
