Abstract

Silver-cladding-stainless pipe is used as the supporting tube for the infrared hollow fiber to obtain high durability and strong mechanical strength. For the dielectric inner-coating layer, cyclic olefin polymer (COP) and silver iodide (AgI) are used to lower the transmission loss. The COP layer is formed by using liquid-phase coating method as it is done before. For the AgI layer, liquid-filling technique is developed to reduce the waste liquid of iodine solution. Rigid hollow fiber with optimized COP or AgI inner film thicknesses for CO₂ laser light were fabricated and reasonable transmission losses for an output tip was demonstrated.
