Abstract

Hollow sapphire fibers have been used to deliver up to 1500 W of CO₂ laser power for industrial laser applications. These hollow waveguides incorporate a water jacket to prevent overheating. The fibers are about 110 cm in length and they have been bent to 90 degree(s). The bending loss for the large 1070-micrometers bore fiber is less than 15% of the straight loss.
