Abstract

We studied the influence of H2-loading and subsequent UV-exposure on the photo-luminescence VUV excitation spectra in Ge-doped silica glass. Next, we compare the 193nm laser induced absorption and photo-luminescence excitation changes. We have also investigated the polarization properties of the luminescence in UV-exposed H2-loaded germanosilicate glasses.
