摘要
中红外波段包含了极其重要的大气红外窗口和众多重要分子的指纹区,该波段的光源和光器件在光电对抗、环境监测、生物传感和医疗诊断等领域具有重要应用。作为全光纤化中红外激光的关键元件,中红外玻璃光纤光栅成为人们的研究热点。氟化物光纤光栅、硫系光纤光栅和碲酸盐光纤光栅是目前应用最广泛的中红外玻璃光纤光栅,本文分门别类地对这3种光纤光栅的性能特点、制备工艺、研究现状和应用领域等进行了全面系统的概述,并分析了目前中红外玻璃光纤光栅的优势和局限性,为进一步提升中红外光纤激光器的性能,拓展中红外光纤光栅的应用领域提供参考和借鉴。
The mid-infrared band contains extremely important atmospheric infrared windows and the fingerprint regions of many important molecules. The light sources and optical devices in this band have important applications in the fields of optoelectronic countermeasures, environmental monitoring, biological sensing, and medical diagnosis. As a key component of all-fiber mid-infrared lasers, mid-infrared glass fiber gratings have become a recent research hotspot.Fluoride fiber gratings, chalcogenide fiber gratings, and tellurite fiber gratings are the most widely used mid-infrared glass fiber gratings. This paper gives a comprehensive and systematic overview of the performance characteristics, fabrication process, research status, and application fields of the three kinds of fiber gratings, and analyzes the advantages and limitations of the current mid-infrared glass fiber gratings. It provides a reference for further improving the performance of mid-infrared fiber lasers and expanding the application field of mid-infrared fiber gratings.
