摘　　要：单晶光纤是指具有光学纤维形态的单晶体,其同时保持了玻璃光纤的形态优势以及体块单晶优异的物理和化学性能,为高功率激光应用中替代传统玻璃光纤提供了一种思路。随着单晶光纤在材料种类及应用方向的不断拓展,单晶光纤在辐射探测、高温传感等领域也具有潜在的应用前景。本文在介绍单晶光纤应用背景的基础上,对国内外激光加热基座法单晶光纤生长技术进行了总结,详细讨论了单晶光纤生长过程中存在的问题及其改进方案,最后对单晶光纤未来的发展方向进行了展望。Single-crystal fiber(SCF)is a fiber-shaped monocrystalline material,which maintains the morphological advantage of glass fiber and the excellent physical and chemical properties of bulk single crystal,therefore providing a way to replace traditional glass fiber in high-power laser applications.With the continuous expansion of SCF in material types and application directions,SCF also has potential application prospects in radiation detection,high temperature sensing and other fields.In this paper,based on the introduction of the application background of SCF,the growth technology of SCF by laser heating pedestal growth(LHPG)method at home and abroad is summarized,and the problems in the growth process of SCF and the improvement scheme are discussed in detail,and finally the future development direction of SCF is prospected.
