摘要：

As2Se3 glass fibers measuring 250 mu m in diameter were fabricated based on different draw processing parameters, including preform dropping temperatures ( T-1 = T-g + Delta T, Delta T = 20, 30, 40, 50 degrees C), fiber-drawing temperatures (T-2 = T-g + Delta T, Delta T = 10, 20, 50 degrees C), and drawing speeds. Raman spectra indicated crystallization on fiber surface at high temperatures. After fiber drawing, oxygen was detected on fiber surface by energy dispersive X-ray spectra. High-quality fiber with minimum loss of 1.88 dB/m (at 9.05 mu m) was achieved under optimal dropping temperature of 218.1 degrees C (T-g + 30 degrees C), fiber-drawing temperature of 208.1 degrees C (T-g+ 20 degrees C), and drawing speed of 0.10 m/min.
