LUMINESCENT GERMANATE GLASS Russian patent published in 2010 - IPC C03C3/253

Abstract RU 2383503 C1

FIELD: chemistry.

SUBSTANCE: use of said glass as an active element in lasers (amplifiers) increases generation (amplification) bandwidth and reduces the size of the microchip due to absorption of pumping radiation by the luminescence sensitiser in a thin layer. The luminescent germanate glass contains the following in mol %: GeO₂ 40-60, Er₂O₃ 0.01-5, Yb₂O₃ 1-28, B₂O₃ 15-30, Al₂O₃ 1-5, La₂O₃ 1-25.

EFFECT: increased effective half luminescence emission band in the junction ⁴I_13/2→⁴I_15/2 of ions Er³⁺ (λ~1,55 mcm) and increased concentration of Yb³⁺ ions.
