摘　　要：针对辐照环境下光纤放大器输出性能的退化问题,对光纤放大器进行了辐照损伤后的光致退火实验研究。首先,介绍了辐射对光纤放大器的影响,在总辐照剂量约为280 krad时进行了辐照实验,获知辐射会引起输出功率、光信噪比分别下降7 dB、18 dB;然后,根据光致退火机理,进行了光纤放大器光致退火实验。实验结果表明:光致退火降低了光纤放大器的辐致损耗,与退火之前相比,放大器的输出功率恢复了5.2 dB,输出OSNR恢复了13 dB。Aiming at the degradation of the output performance of optical fiber amplifier in irradiation environment, the photoannealing experiment of optical fiber amplifier after irradiation damage is carried out. Firstly, the influence of radiation on optical fiber amplifier is introduced.The irradiation experiment is carried out when the total irradiation dose is about 280 krad. It is known that the radiation will reduce the output power and optical signal-to-noise ratio by 7 dB and 18 dB respectively. Then, according to the mechanism of photoannealing, the photoannealing experiment of fiber amplifier is carried out. The experimental results show that the radiation-induced loss of the fiber amplifier is reduced by optical annealing. Compared with that before annealing, the output power of the amplifier is restored by 5.2 dB and the output OSNR is restored by 13 dB.
