辐射环境下,增益光纤的辐致损耗会引起激光器输出性能的退化。光漂白是降低辐射影响,恢复激光器输出特性的一种有效方法。文章对掺镱光纤激光器的辐照和光漂白特性开展了实验研究和模拟仿真。在伽马辐照实验中,激光器输出功率出现了明显下降;在漂白实验中,观察到了激光器的性能恢复,即自漂白现象。为了摸清产生漂白效应的具体激光波长,使用915 nm、976 nm、1070 nm和1550 nm等不同波长激光测试了掺镱光纤内部辐致损耗的漂白特性,明确了1 μm波段激光信号是引起掺镱光纤激光器性能恢复的主要因素,而915 nm、976 nm和1550 nm波段信号则无法实现对掺镱光纤的有效漂白。测量了不同泵浦功率下掺镱光纤的漂白曲线,并通过拟合得到了1070 nm光漂白下,掺镱光纤辐致损耗的演化参数。在此基础上,计算给出了在辐照和光漂白条件下,掺镱光纤内部辐致损耗的演化曲线;结合激光器的辐射物理模型,仿真给出了掺镱光纤激光器的功率演化曲线;相关计算和仿真结果与实验测量数据变化趋势一致。相关工作可为光纤激光器在辐射和漂白条件下性能演化预估提供技术支撑。In radiation environments, the radiation induced attenuation (RIA) of the active fiber will induce severe performance degradation to the fiber laser system. One effective way to solve this problem is to bleach the active fiber with pumps at certain wavelengths, namely photo-bleaching. Experiments have shown that, output power of irradiated Yb-doped fiber lasers experiences remarkable recovery with 976 nm pump. However, under 976 nm pump, signals at both 976 nm and 1070 nm co-exist inside of the Yb-doped fiber. And, it can hardly tell which wavelength is responsible for the photo-bleaching process. Here, a one-hundred level Yb-doped fiber laser is irradiated with gamma-ray radiation. During the radiation process, significant output decline from 129 W at 0 Gy to 81 W at 100 Gy is witnessed. Then, self-bleaching test is conducted with 976 nm pump. After 2 h of bleaching, the output power restored to 111 W, corresponding to a recovery ratio of about 37.0%. To verify the specific wavelength responsible for the performance recovery, photo-bleaching characteristics of Yb-doped fiber lasers are investigated under different pump wavelengths including 915 nm, 976 nm, 1070 nm and 1550 nm. Experiments show that, laser signal at 1 μm waveband is the primary cause for the bleaching of Yb-doped fibers, while, the pump at 915 nm, 976 nm and 1550 nm can hardly bleach the irradiated Yb-doped fiber. The RIA recovery curves of Yb-doped fibers under different 1070 nm bleaching powers are measured. And, related evolution parameters are obtained through curve fitting. With these parameters, the RIA evolution of the Yb-doped fiber and the corresponding output power evolution of the Yb-doped fiber laser during the radiation and bleaching process are simulated. Comparisons show that, the numerical results are consistent with the experiments qualitatively, demonstrating the reliability of the model. This work should be instructive for the performance prediction of fiber laser systems under radiation and bleaching environments.
