Abstract
In the paper spectroscopic properties of aluminosilicate glasses co-doped with Nd3+/Yb3+ were investigated. Strong and wide emission in the 1μm region obtained by optimization of Nd3+ → Yb3+ energy transfer corresponding to the superposition of optical transitions Nd3+:4F3/24I11/2 and Yb3+:2F5/22F7/2 (Yb3+) was observed. The construction of double-core, double-clad optical fiber with cores manufactured from the aluminosilicate glass (co-doped with 1st core- 0.15Nd2O3, 2nd core - 0.15Nd2O3/0.45Yb2O3 mol%) was developed. Comparative analysis of shape of luminescence (λp=808 nm) obtained in bulk glass (0.15Nd2O3/0.45Yb2O3) and ASE in double-core optical fiber clearly shows significant differences in luminescent properties. Mechanisms influencing differences in the shape of luminescence of fabricated glass and optical fiber were also discussed.
