红外中空纤维采用不锈钢管作为支撑管，具有较高的耐用性和较强的机械强度。为了降低引起额外传输损耗的不锈钢管内表面粗糙度，采用丙烯酸-硅树脂材料作为不锈钢管内壁的缓冲层，以获得低损耗的特性。对于介质内涂层，使用了环烯烃聚合物(COP)来降低传输损耗。采用液相包覆法形成CoP层。制备了用于CO2激光的COP内膜厚度优化的中空光纤，并证明了其合理的传输损耗。
Stainless pipe is used as the supporting tube for the infrared hollow fiber to obtain high durability and strong mechanical strength. In order to reduce roughness of inner surface of stainless tubes which causes the additional transmission loss, an acrylic-silicon resin material is used as a buffer layer to the inner wall of stainless tube for a low-loss characteristic. For the dielectric inner-coating layer, cyclic olefin polymer (COP) is used to lower the transmission loss. The COP layer is formed by using liquid-phase coating method. The hollow fiber with optimized COP inner film thickness for CO2 laser light were fabricated and reasonable transmission loss was demonstrated.
