摘要: 单晶光纤(SCF) 是一种将体块晶体与玻璃光纤的优势相结合的新型一维化晶体材料, 其具有优异的 物理化学以及热管理性能, 在激光、闪烁、传感等方面具有巨大的应用潜力。目前单晶光纤的主要生长方法 有激光加热基座(LHPG) 法和微下拉(-PD) 法, 其中LHPG 法生长过程中不需要使用坩埚, 可制备更小直径的 单晶光纤,以充分发挥光纤的形态优势。研制了国内具有自主知识产权的LHPG 单晶光纤炉, 并生长了Al2O3、 YAG、LuAG 等单晶光纤, 其中YAG 单晶光纤直径可达200 m, 长度为710 mm, 长径比大于3500:1。同时对单 晶光纤的直径均匀性、结晶质量等性能进行了研究, 结果表明准一维化的单晶光纤仍具有良好的物化性能。

Abstract: Single-crystal fiber (SCF) is a new type of one-dimensional crystal material that combines the advantages of bulk crystal and glass fiber. It has excellent physicochemical and thermal management properties, and has huge application potential in laser, scintillation, and sensing. At present, the two main growth methods of SCFs are micro-pulling down (-PD) method and laser heated pedestal growth (LHPG) method. The LHPG method does not need crucible in the growth process and the SCFs with smaller diameter can be prepared to give full play to the morphological advantage of the fiber. Therefore, the LHPG SCF apparatus with independent intellectual property rights is developed, and Al2O3, YAG, LuAG and other SCFs are grown. The diameter of the YAG SCF can reach 200 m, the length is 710 mm, and the aspect ratio is more than 3500:1. At the same time, the diameter uniformity and crystallization quality of the SCF are investigated, which shows that the quasi-one-dimensional SCF still has good physicochemical properties.
