摘　　要：随着软玻璃光纤的发展和光纤激光器的进步,越来越多的研究人员采用以软玻璃光纤代替石英光纤的方式,得到高功率中红外超连续谱光源。通过广泛阅读国内外关于氟化物玻璃光纤、硫系玻璃光纤和碲酸盐玻璃光纤等软玻璃光纤产生超连续谱的相关文献,本文综述了近年来利用这三类光纤产生中红外超连续谱光源的研究进展。目前氟化物玻璃光纤在实验中的应用最为广泛,且研发进度较快,获得的中红外超连续谱覆盖范围在2~5µm,最大输出功率可达30 W;硫系玻璃光纤产生的中红外超连续谱光源带宽可达10µm以上,但输出功率较低;碲酸盐玻璃光纤由于材料中羟基难以去除,在中红外超连续谱的实验中进展较为缓慢;而氟碲酸盐光纤在近几年发展迅速,可能成为未来中红外超连续谱研究的理想介质。With the development of soft glass fiber and fiber laser,more and more researchers use soft glass fiber instead of quartz fiber to obtain high power mid-infrared supercontinuum source.Through extensive reading of the do-mestic and foreign literatures on supercontinuum generation in soft glass fibers such as fluoride,chalcogenide and tel-lurite glass fibers,the recent progress in the generation of mid-infrared supercontinuum source using these three types of fibers is reviewed.At present,fluoride glass fiber is widely used in the experiment,with the rapid progress in research and development.The spectrum coverage range of mid-infrared supercontinuum source is 2~5µm,and the maximum output power is 30 W.The bandwidth of the mid-infrared supercontinuum source generated by chalco-genide glass fiber can reach more than 10µm,but the output power is low.Because the hydroxyl groups in tellurite glass fibers are difficult to be removed,the progress in the experiment of mid-infrared supercontinuum is very slow.In recent years,the development of fluorotellurite fiber is rapid,and it may become an ideal medium for the future study of mid-infrared supercontinuum.
