Paramagnetic centers and absorption bands in the visible-to-uv region in Ge and Sn co-doped SiO2 glass irradiated with UV photons from a KrF excimer laser were examined. The (Sn4+)- and the Sn E' centers were induced by the irradiation of KrF excimer laser photons. It was observed that the absorption of the (Sn4+)- is around 4.4 and 5.4 eV. Furthermore, it was found that the Sn-related oxygen deficient center has an absorption band around 4.83 eV.
