Abstract

The experimental results are presented for a laser-induced modification of the structure of porous glass (PG) preliminarily doped with an aqueous nitric-acid solution of Bi(NO₃)₃. It is established that the laser-induced local stabilization of bismuth active centers (BACs) in the bulk of PG plates is possible, which is confirmed by the change in the luminescence in the irradiation zone.
