| 摘要 |
The invention relates to a bundle for fiber lasers, wherein two optical fibers (10, 14) attached to each other exclusively by a removable bridging element (11) along a section of their length, the two optical fibers being freed from each other in at least another section of their length. The bridging element comprising silica glass, which has a refractive index essentially the same to that of a material of an outer layer of the two optical fibers, and the bridging element is a sacrificial layer (19) deposited on only one of the two optical fibers, a material of the sacrificial layer being doped so as to increase a wet etching speed of the sacrificial layer as compared to a material of the two optical fibers in order to be more easily removable. |
