Hydrogen-Related Conversion Processes of Ge-Related Point Defects in Silica Triggered by UV Laser Irradiation
F. Messina, M. Cannas
The conversion processes of Ge-related point defects triggered in amorphous SiO2 by 4.7eV laser exposure were investigated. Our study has focused on the interplay between the (=Ge&…
UV-Photoinduced Defects In Ge-Doped Optical Fibers
F. Messina, M. Cannas, K. Medjahdi +2
We investigated the effect of continuous-wave (cw) UV laser radiation on single-mode Ge-doped H2- loaded optical fibers. An innovative technique was developed to measure the optica…
Spectroscopic parameters related to non bridging oxygen hole centers in amorphous-SiO2
L. Vaccaro, M. Cannas, B. Boizot
The relationship between the luminescence at 1.9 eV and the absorption bands at 2.0 eV and at 4.8 eV were investigated in a wide variety of synthetic silica samples exposed to diff…
Nd:YAG laser induced E' centers probed by in situ absorption measurements
M. Cannas, F. Messina
We investigated various types of commercial silica irradiated with a pulsed Nd:YAG laser radiation (4.66 eV), with exposure time ranging up to 10000 s. Transient E' centers were pr…
