Silica-based optical fibers, fiber-based devices and optical fiber sensors are today
integrated in a variety of harsh environments associated with radiation constraints. Under …

Radiation-induced absorption and lasing efficiency of a hermetically coated erbium-doped
fiber saturated with molecular hydrogen are studied. It is shown that H 2-loading of …

We present results of gamma irradiation tests of 200 μm pure silica core optical fibers with a
low and high-OH concentration, with and without hydrogen loading. All the fibers were …

Signal transmission over optical fibers in the ultraviolet to near-infrared domains remains
very challenging due to their high intrinsic losses. In radiation-rich environments, this is …

The mechanisms of radiation-induced absorption in silica optical fibers in the visible spectral
region and in the telecom spectral windows as well as the technological means to lower the …

We studied the efficiency of a hydrogen-treatment in different pure silica core fibres
irradiated by γ-ray in an attempt to decrease the radiation-induced absorption (RIA). It is …

An overview of the results of the irradiation tests on diagnostic components under the ITER
technology R&D tasks and the solutions for the present diagnostic design are given in the …

We report on the radiation assessment of hydrogenated aluminium coated 200μm pure
silica core fibres. It is experimentally demonstrated that hydrogen protected the fibres …

We investigated the darkening of nine high OH− fibre types irradiated with 500 MeV
electrons from the Linac Injector of LEP (LIL) at CERN. The transmission of Xe light was …

It is shown that the service life of erbium-doped fibres can be increased many times under
conditions of an elevated radiation level by loading the fibre glass network with molecular …
