Paper Abstract

In the article the spectroscopic properties of Yb3+/Ho3+ codoped tellurite glass has been investigated. Upconversion luminescence at the wavelengths of 545 nm (5S2 (5F4) → 5I8) and 654 nm (5F55I8) in holmium ion was obtained as a result of energy transfer between Yb3+ and Ho3+ ions. Elaborated tellurite glass characterized by highest intensity of upconversion luminescence (0.5mol% Yb2O3/0.1mol% Ho2O3) was used as core of double-clad optical fiber. The amplified spontaneous emission in the fabricated optical fiber resulting from the optical transition in the structure of holmium was observed. The intensity of the emission band at the wavelength of 545 nm (5S2 (5F4)→ 5I8) of the fabricated optical fiber was several times smaller than the intensity of the emission band at 657 nm (5F55I8).
