摘要
单晶光纤(SCF)即具有光纤形态的单晶体,不仅保持了单晶材料优异的理化性能,而且具备光纤散热效率高的优势和光波导特性,在固态激光、辐射探测、高温传感等领域具有潜在的应用前景。近年来,研究人员在单晶光纤的晶体生长、包层制备技术、器件应用等领域开展了大量研究。本文围绕当前制备氧化物和氟化物单晶光纤广泛采用的微下拉法、激光加热基座法、导模法等晶体生长技术展开详细讨论,论述了上述晶体生长技术的原理和应用特点,并介绍了国内外相关领域科研团队的研究进展。此外,简要介绍了单晶光纤在高功率激光、中红外激光、辐射探测等领域的应用探索,并探讨了单晶光纤的包层制备技术。
Single-crystal fiber(SCF)is a fiber-shaped monocrystalline material,which maintains the outstanding physical and chemical properties of bulk crystals and simultaneously exhibits the excellent thermal dissipation efficiency and waveguide structure of optical fibers,therefore indicating significant potential applications in solid-state lasers,scintillation detectors,high temperature sensors,etc.Recently,numerous researches have been focused on the crystal growth,the fabrication of cladding structure as well as applications of SCFs.In this paper,the characteristics and developments of the most widely applied crystal growth techniques of SCFs,including micro-pulling-down method,laser-heated pedestal growth technique and edge-defined film-fed growth technique,are introduced in detail.Recent progress of several research groups engaging in SCFs both at home and abroad are also discussed.The investigation of applications of SCFs in high-power laser systems,mid-infrared lasers as well as scintillation detectors are analyzed.The strategies of cladding fabrications is also introduced briefly.
