Undoped-silica-core F-doped-silica-cladding optical fibers (“undoped fibers”) are an
important fiber type for applications requiring resistance to ionizing radiation (eg, the nuclear …

Single-mode optical fibres (SMFs) are required for ITER in-vessel applications as transport
fibres to deliver the signal at wavelength λ= 1.55 µm from/to optical fibre sensors. The paper …

In this work, in order to identify the structures of Yb-TMHD (TMHD= 2, 2, 6, 6-tetramethyl-
heptane-2, 4-dionate) and Ce-TMHD in commercialized products which are usually used as …

Radiation-induced absorption (RIA) in a pure-silica fiber (PSF) was investigated at four
wavelengths λ= 659, 828, 1310, and 1550 nm after seven X-ray pulses on the scale 1 μs–2 …

Radiation-induced absorption (RIA) of light in five isotropic optic fibers (OFs) with a core of
undoped silica glass (SiO 2) and a fluorosilicate cladding and one birefringent OF of the …

Radiation-induced attenuation (RIA) in fibers is investigated at λ= 1.55 μm due to pulsed
bremsstrahlung irradiation from an electron accelerator (mean photon energy of~ 5 MeV …

The dependences of the spectra of radiation-induced attenuation (RIA) of light in a pure-
silica core (PSC) optical fiber (OF) during and after gamma-irradiation up to 590 kGy at a …

Spectra of the initial loss and radiation-induced attenuation are compared in pure-silica-core
optical fibers (PSFs) drawn from the same preform with the help of carbon-resistance …

The lowest excited electronic state of the O2 molecule, a1Δg, the “singlet oxygen”, is of
utmost importance for photochemistry and photobiology. For O2 trapped in silica glass, the …

The photoluminescence and decay properties of Yb 3+/Ce 3+ co-doped aluminosilicate
glasses were investigated under ultraviolet irradiation. A strong excitation band was …
