Paper Abstract

As a coating material for the dielectric-coated metallic hollow glass waveguides, a new kind of cyclic olefin polymer (COP-E48R) has been selected. Silver hollow glass tubes coated by this polymer have been successfully fabricated with the length of 2 m and the inner diameter of 1 mm, 700 micrometers , and 540 micrometers , respectively. When the thickness of the COP-E48R layer is properly selected, mid-infrared laser light of CO2, CO, and Er:YAG as well as near infrared Nd:YAG laser has been transmitted with small attenuation. Straight losses of 0.1 to 0.25 dB/m were obtained for Nd:YAG, Er:YAG, CO, and CO2 laser light for the waveguides with the inner diameter of 1 mm. Bending losses of these waveguides were also evaluated for the above laser light.
