摘要：

The study of luminescence of high-purity multicomponent silicate glasses excited by radiation of a N-2 laser (lambda = 337 nm, P approximate to 12 kW) showed darkening of a sample and a monotone decrease in luminescence intensity and the transmitted radiation intensity from pulse to pulse. Additional illumination with radiation of an Ar+ laser (lambda = 514.5 nm) caused an increase in luminescence intensity. An increase in absorption and a decrease in luminescence intensity were found to be caused by two-photon absorption and electron-hole pair production. (C) 2000 MAIK "Nauka/Interperiodica".
