摘要：

1 wt pct Nd2O3-doped tellurite bulk glass and fiber with the same composition of 75TeO(2)-15ZnO-5Na(2)O-5Li(2)O (mol fraction, %) were fabricated. Judd-Ofelt analysis was carried out for the bulk. The emission from the F-4(3/2)-->I-4(13/2) transition in fiber is at 1.33 mum wavelength with a spectral bandwidth of 55 nm, which is similar to that in bulk. In the case of the fiber, the lifetime of F-4(3/2) level is 164 mus, and the quantum efficiency is similar to100%. The figure-of-merit for gain (sigma(o)tau(0)) for Nd3+-doped tellurite glass is about 2.8 x 10(-24) cm(2.)s, which is quite comparable with that in Nd3+-doped fluoroaluminate glasses, and is an order of magnitude larger than Pr3+-doped fluoride glasses.
