一种滤波环结构大芯径传能石英光纤
摘要：
本发明涉及一种滤波环结构大芯径传能石英光纤，所述光纤包含有位于中心的芯层（101），所述芯层（101）外依次包裹有内包层（102）、滤波环层（103）、外包层（104）和涂覆层（105）；且外包层（104）的折射率＜内包层（102）的折射率＜滤波环层（103）的折射率小于芯层（101）的折射率。本发明一种滤波环结构大芯径传能石英光纤，具有较高的光纤端面激光耦合效率和良好的传输效率。
摘要（英）：

The present invention relates to a filtering ring-structured large-core diameter energy transfer quartz optical fiber. The optical fiber includes a core layer (101) located in the center; the core layer (101) is wrapped with an inner cladding layer (102), a filtering ring layer (103), an outer cladding layer (104) and a coating layer (105) respectively; the refractive index of the outer cladding layer (102) is lower than that of the inner cladding layer (102); and the refractive index of the inner cladding layer (102) is lower than that of the filtering ring layer (103). The filtering ring-structured large-core diameter energy transfer quartz optical fiber of the invention has high optical fiber end surface laser coupling efficiency and excellent transmission efficiency.
