Hollow glass waveguides have been fabricated with losses as low as 0.2 dB/m at 10.6 micrometers . These guides were fabricated from polyimide-coated, glass tubing in which we deposited an inside metallic layer followed by a thin dielectric coating to enhance the reflectivity of the metal film. The inner diameters of the tubing ranges from 320 to 700 micrometers and we have made lengths as long as 3 m. The bending radii of the guides is less than 5 cm for bore sizes less than 500 micrometers . We have used these waveguides to deliver over 80 W of CO2 laser and several watts of Er:YAG laser power. Finally, the hollow glass guides are inexpensive, robust, and EtO sterilizable.
