Paper Abstract

A hollow waveguide made from alumina, ceramic tubing has been developed for use in delivering CO2 laser power in laser surgical applications. This hollow fiber is rigid and can deliver in excess of 70 watts of power with spot sizes less than 1 mm. The output beam is nearly TEMoo. with a full divergence angle of less than 3°. The attenuation of the hollow fibers varies from 0.4 to 1.5 dB/m depending on bore size. Using a special coupler, we attach the waveguides to the articulated arm of a CO2 laser. The fiber is then inserted into an endoscope for delivering power into the body.
