It is desirable in many surgical and industrial applications of infrared (IR) lasers to employ a flexible fiber optic delivery system to conveniently distribute energy to remote locations. While many different IR fibers have been developed only a few are suitable for the delivery of laser power. The best fiber candidates for the high power CO2 laser are the hollow metallic and hollow sapphire fibers, and at Er:YAG laser wavelengths the fluoride glass and solid-core sapphire fibers offer the greatest promise. Hollow metallic waveguides have been used to deliver up to 2,600 W of cw CO2 laser power.
