Yb 3+-Er 3+-codoped lithium silicate glass for fiber optics amplifiers are involved in this paper. Absorption from the 4I 15/2 ground state, emission spectra under the excitation of 976 nm laser diode have been performed at room temperature on these materials. The intense emission peak is located at 1.5399 μm, and the full-width at half-maximum (FWHM) is ～50 nm, corresponding to the 4I 13/2→ 4I 15/2 transition of the Er 3+ ion. The results indicate that lithium silicate glass is an attractive material for 1.55 μm optical amplifiers, because it exhibits a high solubility for Er 3+ and Yb 3+ ion, wide-band tenability, superior chemical resistance and compatibility to optical fibers.
