Paper Abstract

In order to gain a better understanding of the optical behaviour of irradiated silica (dry, OH and F-doped) two spectroscopic methods are used. In the first case an Ar.F laser emitting at 193 nm excites preform samples and the fluorescence is examined between 400 and 1000 nanometers. In the second case fibers drawn from these preforms were excited using an Ar+ laser and examined with a Raman microprobe in the various doped zones. The emission spectra confirm that 02 molecule complexes contribute to the optical spectra of pure silica samples. The presence of fluorine as a dopant seems to be associated to an emission band around 600 nm whose nature is so far unknown.
