Abstract

We have investigated the transient luminescence of silicate glasses irradiated with laser UV. The characteristic time of luminescence decay at room temperature is about 1 mks. We have found a dependence of the intensity and the spectra shape on geometry of irradiation and the sample thickness. We explain this dependence as a result of the luminescence radiation reabsorption with transient radiation defects. On this bases we have developed a model that gave us opportunity to calculate the transient absorption spectra, associated with that defect. These spectra significantly differ from stationary absorption spectra induced with multi- impulse irradiation.
