Abstract
Sapphire optical fibers have been grown using the laser-heated pedestal-growth method with losses as low as 0.3 dB/m at 2.94 micrometers and lengths as long as 5 m. With the incorporation of a computer-controlled feedback system we have been able to grow fibers with less than plus or minus 0.5% diameter variation, or plus or minus 1.5 micrometers for a 300 micrometer fiber. We have been able to decrease the loss in these fibers through a post-growth anneal at 1000 degrees Celsius in air; from 5.4 dB/m to 1.5 dB/m at 543 nm and from 0.4 dB/m to 0.3 dB/m at 2.94 micrometer. These fibers delivered 4.7 W at 10 Hz of Er:YAG laser power.
