The research aimed to study the kinetics of 400 nm blue emission during ultraviolet insolation on germanoslicate optical fiber, hydrogenated, and non-hydrogenataed. The hydrogenation of the fibers was carried out at room temperature under 150 atm for 4 weeks. The focused frequency doubled Argon laser ultraviolet beams were directed to the core of the unsheathed fiber. The light beams emerging from the end of the fiber were directed towards a detector. Kinetics the creation of defects in the hydrogenated fiber followed the power law for low-fluency insolation. At high fluency, the formation of defects followed the principle of two photosensitization or serial steps. © 2018 Sumy State University.
