采用改进的化学气相沉积法制备掺Yb石英光纤预制棒,以该预制棒制备了尺寸为10/130 μm的双包层掺Yb光纤,将这些光纤分成若干组,在不同剂量的60Co γ辐射源下辐照,测试了光纤在辐射前后的吸收谱和激光性能以及光纤预制棒切片辐照后的吸收. 实验结果表明:光纤中已存在的色心缺陷(如氧空位(Ⅱ))和辐照引起的色心缺陷(如E'心、过氧基以及Yb2+离子)等因素的叠加作用可能导致辐照后的光纤在可见光区域的吸收显著增大;与辐照前相比,辐照后光纤的斜率效率、光-光效率显著下降,剂量越大激光性能下降得越厉害;基于Power-Law定理拟合了光纤辐致损耗与所受剂量的关系曲线,定量分析了不同剂量辐照后光纤激光性能下降的原因. 研究结果将为进一步发展抗辐照光纤提供理论和实验依据.

Yb-doped double-clad fibers are prepared through a conventional modified chemical-vapor deposition technique and solution doping method: each fiber contains a core of around 10 μm in diameter. These fibers are divided into groups under 60Co γ radiations of different doses, and we investigate the fiber absorption spectra and laser spectral properties before and after irradiation. Experimental results show that with increasing the irradiation dose the absorption of the fiber after irradiation increases significantly in the visible region, we believe that the enhancement of optical fiber absorption in the visible region may be due to the color center defects existing already in the fiber (such ODC (Ⅱ)) and the color center defects produced by the irradiation (E'center, POR and Yb2+ions). We also analyze slope efficiencies, bare efficiencies, and transmission characteristics of the fiber before and after laser irradiation. Finally, we use the power-law to fit the radiation-induced losses of the fiber under different radiation doses, and the results obtained in this paper provide a theoretical basis for studying the anti-radiation of optical fibers.-
