单晶蓝宝石光纤采用激光加热基座生长方法生长，在 2.94 μm 时损耗低至 0.3 dB/m。通过采用计算机控制的反馈系统，所生长的纤维直径变化小于+/-0.5%，或者300微米纤维的+/-1.5微米。通过在空气中 1000 摄氏度的生长后退火，这些光纤的损耗进一步降低，在 543 nm 处从 5.4 dB/m 降低至 1.5 dB/m，在 2.94 μm 处从 0.4-0.3 dB/m。这些光纤在 10 Hz 频率下提供 4.7 W 的 Er:YAG 激光功率。 (C) 1997 年美国光学学会。
Single-crystal sapphire fibers have been grown with the laser-heated pedestal-growth method with losses as low as 0.3 dB/m at 2.94 mu m. With the incorporation of a computer-controlled feedback system, fibers have been grown with less than +/-0.5% diameter variation, or +/-1.5 mu m for a 300-mu m fiber. The losses in these fibers have been reduced further through a postgrowth anneal at 1000 degrees C in air, from 5.4 to 1.5 dB/m at 543 nm and from 0.4-0.3 dB/m at 2.94 mu m. These fibers delivered 4.7 W at 10 Hz of Er:YAG laser power. (C) 1997 Optical Society of America.
