摘　　要：随着红外光学的不断发展,国防安全、生物医疗、先进制造等领域对红外激光传输的需求越来越迫切,基于非氧化物玻璃的红外传能光纤日益受到重视。硫系玻璃作为一种优秀的红外材料,具有透过范围广、物化性能稳定、易于成纤等特点,是制备红外传能光纤的理想材料之一。介绍了国内外有关红外激光传输用硫系光纤(包括阶跃型光纤和微结构光纤)的最新研究进展,分析了目前存在的问题,指出了下一步的发展方向。Significance As the performance of mid-infrared lasers continues to improve,there occurs an increasing demand for their applications in laser surgery,military,materials processing,and other fields.Compared with spatial optical systems,the use of infrared fibers for laser transmission can greatly reduce the size of an optical system and improve the compactness and reliability of the whole system.For example,in the medical field,a considerable amount of laser surgery is performed using 2.94μm Er:YAG lasers.The Er:YAG laser radiation absorption is very strong because this laser wavelength is practically in the center of the maximum absorption band of cellular water.Since biological tissues contain up to 70%~90% water,the Er:YAG laser is extremely efficient for their high precision cutting and vaporization.In addition,in the military field,another important application for 2μm to 5μm short-wave mid-infrared lasers is infrared countermeasures(IRCM)or laser tactical systems.Transmitting high power infrared lasers by infrared fibers can deflect or dazzle the infrared target seeking system.This application puts a high demand on the power handling capability of the fiber(typically tens of watts).For 5-12μm long-wave mid-infrared lasers,high power CO(5.4μm)and CO_(2)(10.6μm)lasers can be used for laser surgery,industrial cutting,and welding applications.In addition,the transmission of laser power through optical fibers enables remote operation.Due to the characteristics of wide infrared transmission,good physical and chemical stabilities,and easily fiberized performances,chalcogenide glass is one of the best materials for infrared laser power delivery fiber.Therefore,as an important infrared fiber,the fabrication and application of chalcogenide glass fiber have been paid much attention at home and abroad.This review introduces the research progresses of domestic and foreign research groups in the preparation and application of chalcogenide fibers(including the step-index fibers and micro-structured fibers)for infrare
