摘要
采用改进的化学气相沉积法(MCVD)与溶液掺杂法相结合工艺制棒并拉丝,成功制备了掺铋双包层石英光纤。测试了光纤吸收光谱及在793nm下的吸收系数,分析了影响掺铋光纤近红外荧光光谱的因素,并在793nm波长激光激发下产生了1 400nm的荧光,半高宽约为150nm。
Bi-doped double-clad silica fiber is successfully prepared by a combining technology of MCVD and solution doping technique. The absorption spectrum of Bi-doped fiber and the absorption coefficient at 793 nm are measured, and the affecting factors that affect Bi-doped fiber near-infrared fluorescence spectrum are analyzed. The results show that fluorescence wavelength is near 1 400 nm and FWHM is about 150 nm with 793 nm laser pump.
