ZnS-coated Ag hollow waveguides are newly proposed and fabricated to realize a durable and nontoxic waveguide for CO2 laser light transmission. The fabrication method is based on rf-sputtering and electroplating techniques and a polyimide tube is used as a hollow mandrel. As a result of measurements, low-loss property of the ZnS-coated waveguide is shown and the beam profile with a sharp energy peak is obtained. The result of the aging test proves good durability of the ZnS-coated Ag waveguide.
