N2 - We studied the effect of Co60 gamma-radiation on the
position and the amplitude of fiber Bragg gratings. These gratings
were written with a femtosecond UV laser in three different fibers,
both intrinsically photosensitive and hydrogen sensitized.We have
found that in contrast with the results obtained on gratings written
with low-intensity UV lasers, the Bragg peak shift under irradiation
is almost independent on fiber type, fiber sensitization or
grating amplitude. The grating strength behavior depends on the
fiber type.
