Abstract
This paper discuss a series of codoped silicate glasses prepared by the melting method. 2 μm emissions of the samples are observed under the pump of 980 nm LD. The Judd-Ofelt parameters () and radiative properties are calculated and analyzed; the spontaneous transition probability can reach . From the fluorescence spectra, the peak absorption and emission cross section of are and , respectively. In addition, we analyze the energy transfer process of level to level. Considering the luminance properties and good thermal property, we indicate that codoped silicate glass is a potential laser glass for the efficient 2 μm laser.
