Abstract
In summary, an optical transportation fiber (10) for transmitting laser beams (S0) comprises at least one fiber core (1), at least one fiber jacket (2, 3) and one sheath (5) encompassing the fiber jacket (2, 3), wherein an interlayer (4), the refraction index of which is lower than a refraction index of the corresponding fiber jacket (2, 3) being in contact with the interlayer (4), is provided between the fiber jacket (2, 3) and the sheath (5). Thereby, the fiber (10) is formed with at least one outputting means (11).
Claims13
Optical fiber for transporting laser radiation with at least one fiber core, at least one fiber jacket and one sheath encompassing the fiber jacket, wherein a interlayer is provided between the fiber jacket and the sheath, wherein a refraction index of the interlayer is lower than a refraction index of the fiber jacket, and at least one outputting means for outputting radiation out of the fiber jacket is provided in the fiber, characterized in that the fiber comprises a contact spot, wherein an adhesive is arranged in the area of the contact spot adjacent to the interlayer.
Method for manufacturing an optical fiber for transporting laser radiation, comprising the steps:
- forming a fiber core,
- forming at least one fiber jacket which is arranged around the fiber core, and
- forming a sheath arranged around the fiber jacket, wherein
- the fiber is formed at least in sections with an interlayer between the fiber jacket and the sheath, and wherein
- the interlayer is formed with a refraction index which is lower than a refraction index of the fiber jacket,
- characterized in that the fiber is formed with an interlayer at least in the area of the contact spot.
