Abstract

Aluminum-coated optical fibers are loaded with molecular hydrogen by keeping the fibers in an H₂ atmosphere at high pressure and temperature. A high H₂ concentration in the fiber glass (up to 1 at. %) has been obtained by this technique. A drastic reduction of radiation-induced absorption in the visible spectral region in H₂- containing Al-coated fibers is demonstrated. The formation mechanism is the H(I)-center is analyzed.
