Popis:	The results of complex action of X-ray and nanosecond UV laser radiation on alkali-containing silicate glasses are presented. It is shown that X-ray irradiation of glasses forms luminescent color centers in them, which is related to increasing concentration of structural defects in glass network. Laser radiation destroys these defects, which is accompanied by bleaching of glasses and disappearance of luminescence in irradiated regions. The dynamics of glass bleaching under action of laser radiation and the influence of alkali-metal (Li, Na, K) ions on this process are studied. Mechanisms of destruction of color centers by laser radiation are proposed.
