Mid-Infrared Fluoride Glass Fibers-A Short Review

中红外2~5μm波段在气体检测、航天航空、红外对抗、医疗手术等领域具有广泛的应用,由此开展了大量中红外材料的研究。相较于其他中红外材料,柔性可多向传输的氟化物玻璃光纤由于低的声子能量和优异的中红外光谱性能,受到广泛关注。基于此,本文系统介绍了不同氟化物玻璃光纤(如氟锆酸盐玻璃光纤、氟铟酸盐玻璃光纤、氟铝酸盐玻璃光纤等)的研究现状和存在问题,展示了氟化物玻璃光纤中普遍研究的各类组分的结构、物化性能、光谱性能等,重点介绍了激光领域中氟化物玻璃光纤基于不同稀土离子掺杂实现的不同波段的光纤激光器和覆盖不同波长范围的超连续谱光源,并对氟化物玻璃光纤的研究方向和制备工艺探索进行了展望。

The mid-infrared band has a wide range of applications in the fields of gas detection,aerospace,countermeasures,medical surgery,etc..As a result,a large number of mid-infrared materials are investigated.Compared with other mid-infrared materials,fluoride glass fibers have attracted much attention due to its ability of flexible multidirectional transmission,low phonon energy and excellent mid-infrared spectral performance.As a consequence,we introduced the research status and problems of different fluoride glass fibers such as fluorozirconate glass fiber,fluoindinate glass fiber and fluoroaluminate glass fiber.We represented the inside structure,physical and chemical properties,and spectral properties between various glass components.We highlighted the fiber lasers in different wavelengths and supercontinuum laser scources covering different wavelength bands based on various rare-earth ions doping fluoride glass fiber.In addition,we also prospected the future research direction and preparation process of fluoride glass fiber.
