英文摘要	Ho3+/yb3+ codoped lanthanum-tungsten-tellurite (twl) glasses are prepared by melt-quenching method. the judd-ofelt intensity parameters (omega(t) t = 2, 4, 6), radiative transition rates, radiative lifetimes, and branching ratios of ho3+ are calculated based on the absorption spectrum to evaluate the spectroscopic properties of ho3+ in twl glass. the mid-infrared emission of the samples are investigated under the excitation of 980 nm ld. the absorption, emission cross-sections and gain coefficient of ho3+:i-5(7) -> i-5(8) are calculated. the energy transfer processes of yb3+-yb3+ and yb3+-ho3+ are analyzed, the results show that the yb3+ ions can transfer their energy to ho3+ ions with large energy transfer coefficient, and a maximum efficiency of 84%.
