Abstract

Sapphire fibers grown at 20 mm/min in helium, using an improved laser-heated pedestal growth apparatus, have been shown to exhibit very low losses. The laser damage threshold and bending loss of these fibers have been evaluated. The best fiber forms for energy delivery may be a 100-micron diameter fiber with flared ends to increase the power handling capability while retaining the flexibility. Such a fiber has been successfully grown in our laboratory.
