OPTICAL NANOGLASSCERAMICS WITH CHROMIUM IONS Russian patent published in 2018 - IPC G02B1/00 B82B1/00 

FIELD: laser engineering.

SUBSTANCE: using: for use in the manufacture of solid-state lasers, including fiber lasers, and luminescent optical materials. Summary of the invention is the fact that optical nanoglassceramics with chromium ions refers to a lithium-potassium aluminoborate system with ferric ions and has the following composition (mol %): Li₂O 0–15.0; Al₂O₃ 20.0–30.0; K₂O 10.0–20.0; B₂O₃ 40.0–60.0; Sb₂O₃ 0–6.0; Cr₂O₃ 0.05–0.2.

EFFECT: technical result: simplified manufacturing technology, as well as increased transparency in the visible spectrum.
