摘要
This paper discuss a series of Ho3+/Yb3+ codoped silicate glasses prepared by the melting method. 2 mu m emissions of the samples are observed under the pump of 980 nm LD. The Judd-Ofelt parameters (Omega(lambda)) and radiative properties are calculated and analyzed; the spontaneous transition probability can reach 78.71 s(-1). From the fluorescence spectra, the peak absorption and emission cross section of Ho3+ are 2.36 x 10(-21) and 5.05 x 10(-21) cm(2), respectively. In addition, we analyze the energy transfer process of Yb3+: F-2(5/2) level to Ho3+: I-5(6) level. Considering the luminance properties and good thermal property, we indicate that Ho3+/Yb3+ codoped silicate glass is a potential laser glass for the efficient 2 mu m laser.
