摘　　要：为了分析掺镱有源光纤在辐射环境下的适应性,对制作的20/400μm掺镱有源光纤进行了60 Co为辐射源的高剂量的γ射线辐照试验。试验结果表明在总剂量为200krad(2kGy)高剂量辐照下掺镱光纤的915nm和976nm两个特征吸收波长基本保持不变,光纤掺Ce后提高了耐辐射性能,辐照前后光纤强度衰减不明显。In order to analyze the adaptability of ytterbium-doped active fiber in the radiation environment,the high doseγ-ray irradiation experiment with 60 Co as the radiation source is carried out on the 20/400μm ytterbiumdoped active fiber.The experimental results show that the characteristic absorption wavelengths of 915 nm and 976 nm of ytterbium-doped fiber remain basically the same under the high irradiation dose of 200 krad(2 kGy),and the radiation resistance of the fiber is improved after the fiber is doped with Ce,and the tensile strength attenuation of the fiber is not obvious before and after irradiation.
