Hollow alumina fibers for CO2 laser delivery systems

Christopher C. Gregory, James A. Harrington

Research output: Chapter in Book/Report/Conference proceedingConference contribution


An articulated arm containing hollow-alumina waveguides has been developed for use with surgical, carbon-dioxide lasers. It has been demonstrated that this arm has excellent pointing ability and it can be used with micromanipulators, handpieces, and endoscopic-waveguides. This arm incorporates lower cost materials and much shorter assembly and alignment times than conventional articulated arms. A separate system has been developed for the combining of a carbon-dioxide laser beam delivered by an articulated arm with a Nd:YAG laser beam delivered by a fiber and the launching of the combined beams into an endoscopic alumina waveguide. This system can deliver more then 85% of the CO2 and over 40% of the Nd-YAG radiation to tissue.
