医用红外激光器急需配用的光纤促进了红外光纤的发展 1976年美国休斯研究所挤出了第一根多晶红外光纤。自那以来,人们不断地致力于开发适用于传感器、功率传输以及长距离通信系统的高可靠、低损耗红外光纤。但是这种光纤的损耗大大超过普通石英光纤的最小损耗值(0.2dB/km),而且从本质上讲,它的机械特性亦较差。尽管红外光纤有这么些不足之处,但它的发展依然十分迅速,因为在红外激光系统和必须把信息传至遥控光电检测器的传感器系统中,红外光纤具有一些重要优点。目前,研制红外光纤的主要推动力是对
Urgent need of medical infrared laser equipped with optical fiber to promote the development of infrared fiber Hughes Institute in 1976 extruded the first polycrystalline infrared fiber. Since then, people are constantly working on developing highly reliable, low loss infrared optical fibers for sensors, power transmission and long range communications systems. However, the loss of this kind of optical fiber greatly exceeds the minimum loss value (0.2dB / km) of ordinary quartz optical fiber, and in essence, its mechanical properties are also poor. Despite its shortcomings, infrared fibers are still being developed rapidly because infrared fibers have some important advantages in infrared laser systems and in sensor systems where information must be transmitted to a remote photodetector. At present, the development of infrared fiber is the main driving force
