Influence of H2-treatment and water content on the recovery characteristics of undoped core fibers after pulsed and continuous irradiation
Abstract
The OH-content of an undoped core all-glass fiber is modified within the range from 1 to 100 ppm. At 860 nm wavelength the radiation resistance expressed by recovery coefficient in the long-term annealing after pulsed irradiation (10 ms - 10 s) increases with increasing water-content and with additional hydrogen-treatment. At 1310 nm wavelength the induced loss at short times after the radiation pulse is smaller due to hydrogen-treatment. The long-term recovery decreases with increasing OH-content, in contrast to 860 nm. (INT)
