摘要：
Spectroscopic properties of Er3+ doped various glasses,are investigated experimentally on the basis of Judd-Ofelt theory, McCumber theory, and lifetime measurements. A strong correlation is observed between glass composition and spectroscopic parameters such as Judd-Ofelt intensity parameters Omega(t) (t=2, 4; 6), emission spectra, and lifetime of 41 I-4(13/2) level of Era,. The emission parameters of Er3+ doped various glasses are discussed from the viewpoints of emission and gain characteristics at the 1.55mum bands. The results show that tellurite glass is an indeed promising material for Er3+. doped to realize broadband and high gain amplification.
