A technique is proposed for the formation by a laser beam of nanostructured waveguides with broadband luminescence in the near-IR region with a maximum at 1300 - 1450 nm, in glass with the composition (molar content,%) 7.5 Li 2 O; 2.5 Na 2 O; 20 Ga 2 O 3 ; 35 GeO 2 ; 35 SiO 2 alloyed with 0.1 - 0.5% NiO. A self-limiting mechanism of laser heating is demonstrated, which prevents further growth of the formed nanocrystals. The results of the study are of interest for the development of active elements of integrated optics.
