Abstract

The light transmission characterizes of the optical fiber was changed when it has been exposed in the radiation environment due to the radiation induced defects and the formation of color centers. On the other hand, the damage of crystal lattice was recombined simultaneously due to the effect of light or thermal when the color centers were forming. Moreover the effect assisted by light is commonly called photobleaching which is directly proportional to the light power and inversely proportional to the light wavelength. Based on the effect, the radiation induced loss can be reduced by emitting high-power light to fiber. In this paper, the active recovery effect has been put forward to reinforce the fibers' radiation resistance using two sources after the detailed analysis of the fiber radiant effect and color center model. In addition, the application importance of the methods was also discussed.
