“…The energetic radiation seems capable of affecting the structure of the material, breaking bonds, ionizing electrons, displacing atoms. In particular, as discussed later, it induces the creation of defects in the material [14,15,16,17]. Indeed, there has been a lot of work done on the absorption induced in optical fiber by such energetic radiation, in particular with the aim of developing radiation resistant fibers [18].…”

Optical fiber exposed to high-pressure hydrogen gas for 3–4 days, and subsequently heated in air at temperatures in the range 250–500 °C for 8–24 h, shows an enhanced second-harmonic conversion efficiency after seeding with 1.06 μm and 532 nm light, when compared with untreated fiber seeded under similar conditions. Up to now, an enhancement by as much as a factor of 4.4 has been observed. Some possible correlations between this enhancement and the change in the defect content of the fiber due to the H2 -heat treatment are pointed out.
