LUMINESCENT GLASS Russian patent published in 2011 - IPC C03C3/15 C03C4/12 

FIELD: physics, optics.

SUBSTANCE: invention relates to optical materials, particularly, to optical glass compositions to be used as active bodies of laser (fiber laser included) generating in orange-red region of the spectrum. Proposed allows using proposed material as active body for miniature lasers generating in orange-red region of the spectrum. Proposed luminescent glass comprises B₂O₃, Al₂O₃, La₂O₃ or Y₂O₃ and Sm₂O₃ at the following ratio of components in gram-mol: 65-73 - B₂O₃, 15-20 - Al₂O₃, 8-15 - La₂O₃ or Y₂O₃, 0.1-4 - Sm₂O_3.

EFFECT: luminescent glass suitable for pumping by LEDs that features wide luminescent bands in orange-red spectrum region.
