We present results of an experimental investigation of the optical losses produced by bending large core optical fibers, typical of those used in power beam delivery systems. Experiments have been conducted over a range of core diameters for both plastic clad silica and all-silica fibers as a function of bend radius. A theoretical model has been developed for predicting the magnitude of the bend loss, and agreement was obtained with the experimental results. The study thus yields design information for fiber beam delivery systems.
我们展示了对大芯径光纤弯曲所产生光学损耗的实验研究结果，这种光纤是能量束传输系统中常用的典型光纤。针对塑料包层石英光纤和全石英光纤，在一系列芯径范围内，研究了弯曲损耗与弯曲半径的函数关系，并进行了实验。已开发出一个理论模型来预测弯曲损耗的大小，该模型与实验结果相符。因此，这项研究为光纤束传输系统提供了设计信息。
