Er3+-doped lutetium borosilicate glass for optical signal amplification at 1.5 μm

摘要: A new glass of Lu 2 O 3 -B -SiO -Na O-Er system is prepared by the technique high-temperature melting at different temperatures and formation range experimentally obtained. Effects B content on infrared spectral properties such as 1.5 μm emission bandwidth corresponding to 4 I 13/2 → 15/2 transition Judd-Ofelt parameter Ωt (t = 2, 4, 6) Er 3+ ions in has been observed. The exhibits big integrated cross sections for band. Excellent thermal stability demonstrated using differential analysis. -doped lutetium borosilicate a great candidate broadband erbium doped fiber amplifiers.
