Optical-absorption and emission spectra and fluorescence lifetimes were measured for Nd/sup 3 +/ in tellurite glasses containing various alkali and higher valence state cations and in a series of new phosphotellurite glasses. Judd-Ofelt intensity parameters were determined and used to calculate radiative lifetimes and stimulated emission cross sections for /sup 4/F/sub 3/2/..-->../sup 4/I/sub 11/2/ and /sup 4/F/sub 3/2/..-->../sup 4/I/sub 13/2/ transitions. Cross sections for several of the glasses are the largest obtained for any pure oxide glass. The dependence of the spectroscopic properties on composition and the application of tellurite glasses for lasers are discussed.
