Nd3+-doped antimony germanate glass for 1.06 μm fiber lasers
In this work, a multicomponent GeO 2 –Sb 2 O 3 –BaO (BSG) glass is explored to assess its potential for 1.06 μm fiber lasers . The glass-forming region of BSG system is predicted and determined experimentally based on a thermodynamic method. Benefitting from the incorporation of Sb 2 O 3 , this system possesses an exceptionally large glass-forming region, as well as high density and refractive index , wide infrared transmission range and low phonon energy. Furthermore, an efficient near-infrared emission at 1064 nm from Nd 3+ has been realized in this oxide glass with relatively long measured lifetime (200.58 ± 1.24 μs) and large emission cross-section (3.015 ± 0.090 × 10 −20 cm 2 ), indicating that Nd 3+ -doped BSG glass is a promising candidate for laser application in 1.06 μm region.
