Abstract :
The influence of additionally injected short-wavelength photobleaching light on the radiation hardness of Ge-doped graded index fibres working at 1300 nm wavelength is investigated. Predictions are complicated by the fact that more efficient shortwave bleaching light experiences higher radiation-induced loss. Promising results are found for low fibre temperatures (≲-50°C) and bleaching light of about 835 nm wavelength
