| Outline of Final Research Achievements |
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 walls of stainless tubes 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 and Er:YAG laser light were fabricated.
